深基坑加固锚索预应力荷载变化规律的监测分析
Monitoring analysis of pre-stressed load of anchor cables for deep excavations
-
摘要: 通过实际工程锚索预应力荷载变化的系统监测结果及资料分析,探讨了深基坑桩锚支护体系中锚索预应力荷载的锁定瞬时损失、开挖及锚索施工中锚索预应力荷载变化和基坑侧向变形特性。Abstract: Based on systematical monitoring and analysis in practical projects, the loss of pre-stress after lock, load change of pre-stressed anchor cables in excavation and anchor cables during construction and lateral displacement of excavations are monitored and discussed. |
