Project 1. Stability analysis of a slope next to the Bang Lang dam (Thailand XXXXXXXXXXENG 7308 Due date: 20 Sep (week 9), by 4 pm (please submit your report to the library). Weighting 20%. Learning objectives: This activity will provide students with opportunities to develop critical skills necessary to correctly interpret and analyse results of field investigations, select the appropriate parameters to create a slope model, demonstrate the ability to evaluate the stability of natural slopes, and skills needed to produce comprehensive and concise reports. Group A: If your family name starts with a letter from A to G. Introduction. The Bang Lang dam is one of the major hydro dams in Thailand. After its completion, the neighboring slopes began to experience some slope stability issues during rainy seasons. The risk analysis indicated that, if the slope failed, it would affect the major road to the dam as well as the irrigation system. To collect more information about the slope conditions, field investigations were performed. The obtained data are presented below in the forms of maps and bore logs. Your task is to analyse the obtained results, draw a cross-section of the slope, and perform slope stability analysis. You also need to compute the safety factor for the following site conditions 1) “dry season”: when the top soil layer is dry, and 2) “rainfall season”: when the top soil layer is saturated (the groundwater level is 0.5 m below the ground surface). You need to present and discuss your findings in the form of a report (max 10 pages, excluding references and appendix). Report structure (optional): 1. Executive summary. 2. Introduction (What is the problem? What is your task/objective? What type of investigation was performed, and what results were obtained?). 3. Description of the study area (Interpret and analyse the obtained data, draw a cross-section (A-A’), and discuss the properties of soil and rocks). 4. Slope stability...
