大型地下工程抗浮锚杆监测与受力机理分析

Anti-fl oating Anchor Monitoring and Load-bearing Mechanism Analysis of Large Underground Engineering

以兰州市某大型地下工程抗浮锚杆监测为依托,通过有限元软件模拟分析该工程不同区域的受力情况,将模拟结果与锚杆内力监测结果进行对比分析,以确定该工程地基受力情况的准确性。通过长期监测数据分析抗浮锚杆在不同受力区域的受力规律、不同埋深位置的受力情况以及引起锚杆内力发生变化的主要影响因素,确保工程后期施工的安全性。

Based on actual engineering for long-term monitoring of anti-floating anchor in Lanzhou,this paper analyzed the force situation of different regions of the project though the finite element software simulation,made comparative analysis between simulated result and anchor internal force monitoring results to determine the accuracy of engineering foundation stress distribution. Through the anchor field monitoring and finite element simulation data,to provide reliable reference for future similar projects,and provided the relevant experience for the construction,ensured the project later construction safety.
