【摘要】 该滑坡体位于墨竹工卡县中学后山,318国道正上方。其松散堆积物土方量巨大,有关部门多次进行抗滑防治处理,但均未彻底根治,整个滑坡体仍欠稳定,对中学师生的生命财产安全及公路的安全营运造成极大的威胁。本文通过野外实地勘察,室内岩心试验,采用瑞典条分法计算滑坡的稳定性,并运用FLAC3D数值模拟各种工况下的滑坡体的稳定情况。结果表明:该滑坡体在正常情况下处于稳定状态,在五级以上地震或暴雨下,该滑坡体将失稳下滑。更多还原

【Abstract】 The landslide is located in the hills behind Maizhokunggar County middle school,318 national road, directly above. There is large loose deposits on it,although the department concerned has taken anti- sliding measures many times,it is still not thoroughly eradicated and the whole of landslide still slow down,It has brought significant threats and hazards to teachers and students’ lives and property and Safe operation of the highway. This paper calculates the stability with Sweden slice method by field surveys、core test and use FLAC3 D software to simulate the stability of the landslide on different conditions. It turned out that the landslide is stable in natural state and the landslide will fall under earthquakes of Ms≥5 or heavy rain.更多还原
