格形地连墙结构在紧邻民房建筑边坡支护中的应用

Application of Grid Connected Wall Structure in Slope Support of Adjacent Residential Buildings

采用PLAXIS 3D-HSS模型,考虑土体的小应变刚度特性,分析格形地连墙支护结构在紧邻民房建筑边坡支护的应用过程中支护结构及周边建筑物的变形情况,并将理论分析结果与变形实测数据进行对比。分析结果显示,数值模型计算结果与实际监测数据较为吻合,真实地反映了边坡在开挖过程中对紧邻民房建筑的影响情况;研究成果可为支护高度大且坡顶存在对变形和沉降敏感的建(构)筑物等类似环境条件下的边坡支护工程提供了一定的参考价值。

Using the PLAXIS 3D-HSS model and considering the small strain stiffness characteristics of soil,the deformation of the support structure and surrounding buildings during the application of the grid connected wall support structure in the slope support of adjacent residential buildings is analyzed,and the theoretical analysis results are compared with the measured deformation data.The analysis results show that the numerical model calculation results are in good agreement with the actual monitoring data,which truly reflects the impact of the slope on adjacent residential buildings during the excavation process;This research result can provide certain reference value for slope support engineering under similar environmental conditions,such as buildings(structures)with high support height and sensitive deformation and settlement at the top of the slope.
