摘要:
通过对青海省内一条北北西向右旋走滑断裂对公路工程危害现象的野外实地调查和室内有限元分析,对其蠕滑运动下的致灾机理进行了讨论。结果表明,断层蠕滑作用下的灾害多分布在上盘,且上盘公路南半侧多发张剪性破裂,北半侧多发压扭性破裂,交汇位置的先期破裂是由南侧路沿开始并向路内扩展的。
Abstract:
Based on the field investigations and the indoor finite element analysis to a NNW-trending right-lateral strike-slip active fault which caused the road engineering hazards in Qinghai Province. The road hazard mechanism which caused by the creep motion of the active fault was discussed. The result showed that road hazards were mainly distributed in the upper wall; shear cracks in these places were in the south; and compresso-shear cracks were in the north; the early crack in the intersection started from the south of the highway and then extended to the middle.
