湿地地区桩基竖向承载力研究

为了研究湿地地区桩基实际受力过程,通过试桩的静载试验数据,综合考虑桩周的地质状况,分析了桩身轴力、桩端反力的分布情况,以及桩周侧摩阻力沿桩身的传递规律,试验表明：试桩为摩擦桩,单桩竖向承载力主要由侧摩阻提供,桩端反力很小,设计时可以不考虑桩端反力进行计算。

Study on vertical bearing capacity of pile foundation in wet region

In order to study actual stress process of pile foundation in wet region,through the static load test data of the testing pile,and considering geological condition surrounding the pile,it analyzes axial force of the pile,distribution condition at the end of pile,transmission law of side modulus resistance along the pile.Tests show that when the testing pile is rubbing pile,vertical bearing capacity of single pile is mainly provided by side modulus resistance,the reverse force at the end of pile is rather small,and reverse force at the end of pile can not be considered in the design.
