摘要:瑞丰大酒店东侧停车库工程位于瑞安市,其基坑形状近似长方形,周边延长米约250米,长约104米,宽约21米,开挖土方开挖面积约为2122平方米,开挖土方量约2.4万立方米,采用钻孔灌注桩围护结构。本文以该深基坑工程为研究背景,采用ABAQUS软件建立该基坑工程的有限元模型,进行有限元计算,将模拟数据与基坑监测结果进行动态对比分析,指导下一工况的施工,以保障基坑及周边建筑安全。
Abstract: The parking garage project on the east side of Ruifeng hotel is located in Ruian City. The shape of its foundation pit is approximately rectangular, with an extension of about 250 meters around, a length of about 104 meters and a width of about 21 meters. The excavated earth area is about 2122 square meters, and the excavated earth volume is about 24000 cubic meters. It is enclosed by bored cast-in-place piles. This paper takes the deep foundation pit project as the research background, uses ABAQUS software to establish the finite element model of the foundation pit project, carries out finite element calculation, dynamically compares and analyzes the simulation data with the foundation pit monitoring results, and guides the construction of the next working condition, so as to ensure the safety of the foundation pit and surrounding buildings.
