地震力作用下基覆边坡模型试验研究
Experimental research on seismic failure mode and supporting for slope of bedrock and overburden layer
摘要
Abstract
According to the site investigation of Wenchuan disaster area's statistics data as the background, the experiment model is made selecting Yugongmiao slope as the reference. The similarities of main parameters are analyzed based on dimensional analysis. The underwater blasting is used to simulate seismic wave (near-field), and a large number of model tests are conducted. The results show that the failure model of bedrock and overburden layer slope under seismic loading is surface loose media flowing caused by the tension of superficial layer, and with the increase of explosives (seismic intensity), seismic accelerations increase. It is very useful to design of gravity retaining wall and pile-wall structures. These conclusions can provide some bases for analysis and research of high-steep slopes along railways and highways.关键词
