摘　　要：为了充分了解钻孔灌注桩利用护壁泥浆特性对桩基的承载性能产生的影响,文章主要针对钻孔灌注桩中护壁泥浆的配制、护壁泥浆的作用以及护壁泥浆的功能等方面来对桩基承载性能产生的影响进行分析。同时为了保证桩基础承载力的稳定,我们将从施工的方面进行入手,由此得出一些具体结论。例如:因为护壁泥浆的质量将会对桩端沉渣的厚度以及桩侧泥皮的厚度产生直接的影响,便会间接的对桩基的承载性能造成影响,所以在进行分析计算的时候,对于泥浆质量的选取必须的采取一定的方式。因此,文章对于护壁泥浆的配置原则与配置的方法,在施工管理与安排等各方面进行了一定的总结。in order to fully understand the influence of the use of wall mud characteristics of bored pile on the bearing capacity of pile foundation,this paper mainly analyzes the influence on the pile foundation bearing performance in terms of the preparation of the protective mud in the bored pile,the role of wall mud and the function of the protective mud.At the same time,in order to ensure the stability of the bearing capacity of pile foundation,we will proceed from the construction aspects and draw some concrete conclusions.For example,because the quality of retaining mud will have a direct impact on the thickness of the sediment at the pile end and the mud skin at the pile side,which will indirectly affect the bearing capacity of the pile foundation.Therefore,it is necessary to adopt certain methods to select the mud quality in the analysis and calculation.Therefore,this paper summarizes the configuration principle and method of the wall protection mud as well as the construction management and arrangement.
