岩土边坡地震破坏原理及稳定性研究

摘要

通过对地震的破坏原理、土质边坡条件的研究，分析了岩土边坡在地震作用下的稳定性，并应用有限差分软件FLAC3D计算应力场各点的安全系数，编程绘制安全系数云图并进行分析。研究得到安全系数不严格符合正余弦规律，曲线呈现一定的不规则性。进一步分析得到，此不规则曲线是地震时边坡所受力的随机性带来的结果。%By analyzing the principle of earthquake damage and the soil slope condition , it studied the rock-soil slope stability under the earthquake in this paper .By using the finite difference software FLAC3D ,the safety factor stress field was calculated at each point and through computer programming , safety factor of slope contours were drawn and analyzed .Research results showed that the safety factor is not fit for the Sine and Cosine law ,the curve reveals a certain irregularity .Further research showed that the irregular curve was the results of the stress random of slope in the earthquake .
