"The book comprises select proceedings of the 2016 annual conference of the Indian Geotechnical Society (IGC 2016), with technical papers on the theme “Ground Improvement and Geosynthetics”. The papers cover a wide range of topics, including chemical modification using admixtures, microbial-induced carbonate precipitation, geopolymers, fly ash and other industrial wastes, modification using geosynthetic materials such as natural and synthetic fibers, expanded polystyrene (EPS) geofoam, prefabricated vertical drains, geosynthetic encased-granular columns and mechanical densification through sand columns. This book is a valuable reference for researchers and practicing engineers alike."

"The book comprises selected proceedings of the 2016 annual conference of the Indian Geotechnical Society. The technical papers presented on the theme “Geotechnical Characterisation and Geoenvironmental Engineering” highlight the modified geotechnical properties of soil admixed industrial waste and also the characteristics of soil with different pore fluid under varying test conditions. The major topics covered are (i) characterisation of soils, rocks and synthesised materials and (ii) geoenvironmental engineering and behaviour of unsaturated soil. This book will prove a valuable reference for researchers and practicing engineers alike."

"This book comprises select proceedings of the annual conference of the Indian Geotechnical Society. The conference brings together research and case histories on various aspects of geotechnical engineering and geoenvironmental engineering. The book presents papers on geotechnical applications and case histories, covering topics such as (i) shallow and deep foundations; (ii) stability of earth and earth retaining structures; (iii) rock engineering, tunneling, and underground constructions; (iv) forensic investigations and case histories; (v) reliability in geotechnical engineering; and (vi) special topics such as offshore geotechnics, remote sensing and GIS, geotechnical education, codes, and standards. The contents of this book will be of interest to researchers and practicing engineers alike."

"This book presents selected papers from the International Symposium on Geotechnics for Transportation Infrastructure (ISGTI 2018). The research papers cover geotechnical interventions for the diverse fields of policy formulation, design, implementation, operation and management of the different modes of travel, namely road, air, rail and waterways. This book will be of interest to academic and industry researchers working in transportation geotechnics, as also to practicing engineers, policy makers, and civil agencies."

"This book gathers selected proceedings of the annual conference of the Indian Geotechnical Society, and covers various aspects of soil dynamics and earthquake geotechnical engineering. The book includes a wide range of studies on seismic response of dams, foundation-soil systems, natural and man-made slopes, reinforced-earth walls, base isolation systems and so on, especially focusing on the soil dynamics and case studies from the Indian subcontinent. The book also includes chapters addressing related issues such as landslide risk assessments, liquefaction mitigation, dynamic analysis of mechanized tunneling, and advanced seismic soil-structure-interaction analysis. Given its breadth of coverage, the book offers a useful guide for researchers and practicing civil engineers alike."

"Akibat hujan deras yang terus turun selama lebih dari 3 jam, lereng penyangga rel kereta di Cilebut, Bogor, mengalami kelongsoran. Kelongsoran menyebabkan rel kereta jalur Bogor menuju Jakarta menggantung dan tidak dapat dilalui, empat tiang listrik rubuh, serta puluhan rumah warga yang berada di bawahnya mengalami kerusakan. Sebagai upaya mengidentifikasi faktor penyebab kelongsoran tersebut, dilakukan analisis kestabilan pada lereng tersebut berdasarkan beberapa variasi pembebanan dengan melihat pengaruh rembesan atau seepage akibat keberadaan sungai yang letaknya tidak terlalu jauh dari lereng. Analisis seepage dilakukan dengan menggunakan metode steady-state, sementara analisis stabilitas lereng menggunakan metode limit equilibrium. Dari hasil analisis stabilitas lereng, kondisi sebenarnya ketika terjadi longsor yaitu saat terjadi hujan dan hanya ada beban kendaraan memang sudah menunjukkan kondisi yang cukup kritis dengan faktor keamanan mendekati 1.000, sementara kondisi yang paling kritis berdasarkan hasil analisis adalah ketika terdapat luapan air dari sungai akibat hujan dan terjadi gempa, serta ada kereta yang melintas di jalur arah Jakarta dengan faktor keamanan sebesar 0.965. Kondisi yang paling kritis dari hasil analisis tersebut kemudian menjadi acuan dalam merencanakan alternatif perkuatan lereng dengan menggunakan soil nail dan geotextile. Kenaikan muka air tanah akibat hujan, pembebanan di area lemah, serta adanya getaran akibat gempa merupakan beberapa hal yang menyebabkan kondisi lereng menjadi tidak aman.

After heavy rains fell for more than 3 hours, slope that supports railway tracks in Cilebut, Bogor, suffered a landslide. This landslide/slope failure made Bogor-to-Jakarta track to hang and cut, four electric poles collapsed, and dozens of houses were damaged underneath. As an effort to identify factors causing the landslide, slope stability analysis is applied to the slope with some loading variations and considering the effect of seepage from a river near the slope.

Seepage analysis is done using steady-state method, while slope stability analysis is done using limit equilibrium method. From the results of slope stability analysis, the actual condition in the event of landslide occur when rain falls and there is only vehicle load already shows considerable critical condition with a safety factor close to 1,000, while the most critical conditions based on the results of the analysis is that when there is a surge of water from the river due to long-duration rain, a train passing Bogor-to-Jakarta track, and an earthquake, with a safety factor of 0.965.

The most critical conditions of the analysis are then become a reference in planning alternatives for slope reinforcement using soil nail and geotextile. Rise in groundwater levels due to rain, loading in the weak area, and the vibrations caused by the earthquake are several things that cause slope condition becomes unsafe."

"This science comic presents the entire life cycle of the metro system in an accessible and fun way. Just like human beings, a metro system can get sick, and this book introduces its ailments, medical records along with experts’ diagnoses and available treatments. Using cartoons, it enables readers of all levels to quickly understand the scientific secrets behind the metro system. It is based on the results of China’s 973 program, which aims to promote and develop basic scientific research in China."
