| 摘 要： | 利用有限元程序对青岛某浅埋大跨地下商场扩建工程的开挖支护过程进行了三维数值模拟，分析了围岩中的位移、塑性区、应力分布及支护的受力状态，从理论上验证了根据工程类比法确定的先拱后墙开挖方案及采用长锚索、短锚杆，以锚为主的锚喷网加固方案的合理性。

| Abstract: | D numerical simulation study was made by finit element program on the excavation and support process of a shallow-lying large span underground market expansion project in Qingdao. The displacement, plastic zones, stress distribution and the stress status of support were analysed. The rationality of the excavation and support scheme determined by engineering analogue method was proved theoretically, providing beneficial experiences for similar underground design and construction. |
