【摘要】 本研究对象为某核电厂取水泵房基坑边坡。根据边坡设计的开挖支护方案,采用ANSYS有限元数值模拟软件,对边坡的开挖支护过程进行了仿真数值模拟。模拟结果表明,在边坡采用深搅桩加固、支护桩、预应力锚索等工程措施后,上台边坡和基坑边坡开挖后引起的位移和应力均较小,边坡处于稳定状态。更多还原

【Abstract】 The research simulates the excavation and supporting of pit slope of the pumproom in XNPC. According to the designing of excavation and supporting plan of slope,the numerical simulation of excavation and supporting of pit slope is conducted using the ANSYS finite element numerical simulation software. The simulation results show that, the displacement and stress caused by the excavation of above stage slope and pit slope are both small after taking some measures,including deep mixing pile reinforcement,retaining piles and prestressed anchor cable. Thus the slope is steady.更多还原
