【摘要】：隨著我國西南地區(qū)水電建設(shè)的不斷發(fā)展，該地區(qū)的水庫不斷增多，水庫庫岸滑坡成為了該地區(qū)主要的工程地質(zhì)問題。通過多種監(jiān)測手段對(duì)庫岸滑坡進(jìn)行監(jiān)測，并用監(jiān)測數(shù)據(jù)結(jié)合有限元軟件的模擬對(duì)庫岸邊坡穩(wěn)定性進(jìn)行分析。本文依托“雅安地區(qū)地質(zhì)災(zāi)害監(jiān)測預(yù)警示范”項(xiàng)目對(duì)四川漢源紅巖子滑坡進(jìn)行庫岸邊坡的穩(wěn)定性研究。通過實(shí)地調(diào)查、監(jiān)測數(shù)據(jù)分析、數(shù)值模擬以及理論分析主要取得如下成果： 1.結(jié)合紅巖子滑坡的水文地質(zhì)、工程地質(zhì)條件及監(jiān)測數(shù)據(jù)，，分析了影響滑坡穩(wěn)定性的主要因素； 2.結(jié)合滲流理論用有限元軟件模擬了降雨、地震、庫水位變化等因素對(duì)滑坡穩(wěn)定性的影響，并分析了其影響過程和程度； 3.通過有限元數(shù)值模擬軟件進(jìn)一步模擬了庫水位不同升降速度下紅巖子滑坡內(nèi)的滲流情況及邊坡的安全系數(shù)，深入的探討了庫水位變化和庫岸邊坡穩(wěn)定性的內(nèi)在聯(lián)系，并進(jìn)一步研究了庫岸滑坡的基本特性，為庫岸滑坡的預(yù)測和防治提供了可靠的依據(jù)。
[Abstract]:With the continuous development of hydropower construction in southwest China, the number of reservoirs in this area is increasing, and the landslide of reservoir bank has become the main engineering geological problem in this area. The stability of reservoir bank slope is analyzed by using monitoring data and finite element software simulation. Based on the project of "geological hazard monitoring and early warning demonstration in Ya'an area", the stability of reservoir bank slope of Hongyanzi landslide in Hanyuan, Sichuan Province is studied in this paper. Sex research. Through field investigations, The main results of monitoring data analysis, numerical simulation and theoretical analysis are as follows:. 1. Based on the hydrogeology, engineering geological conditions and monitoring data of Hongyanzi landslide, the main factors affecting the stability of the landslide are analyzed. 2. Combined with seepage theory, the influence of rainfall, earthquake and reservoir water level on landslide stability is simulated by finite element software, and its influence process and degree are analyzed. 3. The seepage in Hongyangzi landslide and the safety factor of the slope are further simulated by the finite element numerical simulation software, and the internal relation between the variation of reservoir water level and the stability of bank slope is discussed deeply. The basic characteristics of reservoir bank landslide are further studied, which provides a reliable basis for the prediction and prevention of reservoir bank landslide.
