| 摘 要： | 根据宜昌城区的工程地质条件、地基土特性以及现有的深基坑工程特点,通过大型通用有限元软件ANSYS分别建立了喷锚支护开挖的深基坑模型、桩锚支护开挖的深基坑模型和放坡无支护开挖的深基坑模型,借助ANSYS的"单元生死"功能,模拟了深基坑在上述3种开挖形式下的分步开挖过程,并对模拟结果进行分析,得出了深基坑在分步开挖过程中的...

| Abstract: | Based on the engineering geological conditions of Yichang city and the characteristics of foundation soil and existing deep foundation pit engineering,three different deep foundation pit excavation models are established respectively for anchor-plate support,piles and anchors support and no-support with excavated slopes by the universal finite element software ANSYS.Using the element birth and death function of ANSYS,the simulation of deep foundation pit in the form of three kinds of excavation is achieved;... |
