规范法土钉轴力计算对比分析

Contrastive analysis of soil nail axial force with code method

土钉墙支护结构在目前具有很强的现实意义,由于工程设计人员对土钉受力机理的不同理解,从而选择不同的设计规范,得出不同的计算结果.本文以包头某深基坑工程为实例,使用建筑工程现行的3种规范对上部土钉墙支护结构的土钉轴力计算,对比分析这3种规范法计算结果的差异性,并讨论产生差异性的原因,为以后本地区类似工程提供一些计算参考.

Soil nailing wall supporting structures have very strong practical significance at the present time. The different understanding of the soil nail force mechanism by the engineering designers results in the choice of different design codes, and then different results are obtained. A description of the foundation pit engineering presents in Baotou was presented. The soil nail axial force of the upper supporting structure were calculated by using the three kinds of existing construction codes. The differences among these three codes were compared ,the results were analyzed and the causes of the differences were discussed. Some references were provided for future similar projects in Baotou.
