软土地区桩锚支护结构受力及变形分析

Analysis on Stress and Deformation of Pile-anchor Retaining Structure in Soft Soil

摘要:

通过计算分析及实测数据研究，认为在软土地区采用桩加土层锚杆的支护形式是安全可行的，锚杆抗拔力可以得到保证；另外，支护结构的计算变形曲线和实际相符，但考虑到土的蠕变性，侧向位移计算值和实测值有较大出入。

Abstract:

Based on the calculation analysis and the monitoring data study, the retaining structure with pile + soil anchor in soft soil was determined to be safe and feasible in soft soil area and the anchor pullout resistance can be guaranteed. The calculated deformation curve of retaining structure is close to actual situation. But taking account of the soil creep properties, there are some deviation between the calculation value of lateral displacement and measured value.
