摘要

摘要: 为适应基坑滑坡抢险工程临时稳定性和时间紧迫性需要,在分析钢管微型桩作用基础上,提出了一种钢管微型桩简化设计计算方法。将该方法应用于衡阳某基坑滑坡抢险工程设计中,并利用二维岩土限元分析软件Soilworks对设计方案进行有限元模拟,验证设计方案的可行性。布置三个位移监测点对治理方案进行2个月的现场监测,现场监测反馈治理效果表明：建立的钢管微型桩简化设计计算方法用于基坑抢险工程设计是可行的。该方法简单实用,对后续类似基坑抢险工程设计具有一定的借鉴意义。

Abstract: In order to meet the need of temporary stability and urgency of rescue project of excavation landslide, a simplified method is proposed for micropile design on the basis of the analysis of the role and the existing researches on micropiles. The approach is applied to the design in rescue project of excavation landslide in Hengyang, and the finite element simulation is carried out by using two-dimensional geotechnical analysis software Soilworks to verify the feasibility of the program. Three displacement monitoring points are arranged to monitor the treatment program for two months in the field. The treatment effect of field monitoring feedback shows that the proposed simplified method for steel micropiles is feasible. It is simple and practical, and it has good reference and guidance for the design other similar rescue projects.
