摘要
通过对某深基坑桩锚式支护结构进行现场试验,研究分析了深基坑开挖过程中桩身钢筋应力的分布和变化规律。在开挖过程中,桩身内力随开挖深度的增大而增加,桩身钢筋应力与基坑的暴露时间,桩体位移及预应力锚杆的施加有很大关系。
With the site test of the pile and bolt support structure in a deep foundation pit, the paper studied and analyzed the reinforce bar stress distribution and variation law of the reinforced concrete pile in the excavation period of the deep foundation pit. During the excavation period, the inner force of the pile would be increased with the depth of the excavation increased. There were a big relationship between the reinforce bar stress of the pile and the exposed time of the foundation pit, the pile displacement and the pre -stressed bolt.
