基于试验研究的基坑支护安全性分析.

In order to ensure the safety and reliability of the foundation pit support project and the feasibility of the overall construction of the project. Based on the cohesive soil characteristics, this paper mainly uses the inclinometer to measure the displacement of piles and retaining structures and conduct numerical simulation. The results show that during the test period, the excavation support displacement only shows a stable growth mode in the first two months, and then gradually flattens to the final stable state. The safety factor Msf is calculated through numerical simulation, and it is obtained that the reduction of relevant geotechnical parameters makes the safety factor Msf of pile higher than that of retaining structure; And with the increase of time, the pile displacement increment is lower than the support displacement increment.
