摘要
随着人类工程活动范围的扩大,山体滑坡等地质灾害频发。该文通过对江西自然博物馆Ⅱ号山体滑坡的现场调查、勘查及实验测试,详细分析了滑坡的工程地质条件及滑坡特征,结合后缘裂缝位移监测,假设滑面为圆弧,选用瑞典分条法分不同工况对滑坡进行了稳定性计算,结果显示Ⅱ号滑坡在久雨或暴雨的情况下,将处于不稳定状态,以牵引式为主的小型滑坡。由于拟建自然博物馆处于滑坡前缘,结合模拟结果,得出滑坡的潜在滑坡危险性较大,探讨了防治措施,为滑坡的治理提供了参考。
With the expansion of human engineering activities,landslides and other geological disasters frequently occur.This article analyzes in detail the engineering geological conditions and characteristics of the landslide through field investigation,survey and experimental testing of the No.2 landslide in the Jiangxi Natural Museum.Combined with the monitoring of the displacement of the trailing edge cracks,and assumes that the sliding surface is a circular arc.The stability calculation of the landslide was carried out according to different working conditions.The results showed that the No.2 landslide would be unstable under prolonged rain or heavy rain,and it was mainly a small traction type landslide.Since the proposed natural museum is at the front edge of the landslide,combined with the simulation results,it is concluded that the potential landslide risk of the landslide is greater.The prevention and control measures are discussed,which provides a reference for the treatment of the landslide.
