A Geotechnical short course on Slope Stability, Lateral Earth Pressure and Deep Excavation with application of Geo5 softwares

Written by Gouw Tjie Liong, Ir., M.Eng, ChFC, PhD. Posted in Course, Past Courses

Jakarta, 24-26 June 2015


In our practice as geotechnical and civil engineers we are often faced with excessive slope movement and even slope failures; excessive ground movement and failure of deep excavations, be an open cut or supported excavation, is also one of the construction problems we often encountered. Those failures are often caused by lack of adequate geotechnical design knowledge and construction processes. This short course is designed for consulting engineers, contractor, and academican to enhance their knowlege and skill in appreciating important factors affecting the stability of slopes and deep excavations so as to design and execute deep excavation projects safely. Case studies of slope and deep excavation failures shall be presented and discussed. The participants shall have chances to learn how to model a proper slope stability and deeep excavtion analysis by using GEO5 softwares.

Course Topics:

The course shall be conducted by refreshing the basic relevant geotechnical theory, followed by the in depth discussion of geotechnical engineering knowledge and how to implement those knowledge into practice. The course shall cover the following subjects:


  1. SLOPE STABILITY ANALYSIS: Examples of slope failures; Factors affecting slope stability; Slope types; Infinite slope; Planar Failure; Slip Circle Analysis; Fellenius, Bishop Method and Others; Geosynthetics Reinforced Slopes; Earthquake effects. Case studies by using GEO5 Software.
  2. LATERAL EARTH PRESSURES: Various earth retaining structures; Lateral earth pressures and their coefficients; Earth pressure at rest; Rankine, Coulob, Caquot Kerisel lateral earth pressure theories; Load induced lateral earth pressures. Calculation of lateral earth pressures by GEO5 Software
  3. DEEP EXCAVATION: Execution of deep excavation and Its supporting structures covering Soldier Piles, Secant Pile and Diaphragm walls; Ground Anchors, Quality control; Examples of deep excavation failures; Causes of the failures, followed by discussion on the designing and monitoring aspects. Case studies in desingning deep excavation project by GEO5 Softwares.
