当前桩基工程质量合格控制存在的问题与随机控制新模式的探讨

CURRENT PROBLEMS IN QUALITY QUALIFYING CONTROL OF PILE FOUNDATION ENGINEERINGAND APPROACH ON STOCHASTIC CONTROL MODE

研究了当前桩基工程质量合格控制有关规范存在的问题,然后引用概率论和随机抽样推断方法,以及桩基动态检测新技术,提出桩基工程质量合格控制的随机模式——可靠度方法,从而解决了桩基工程质量合格控制模式与建筑结构设计的可靠度方法相一致的理论问题。同时,在实际工程中使桩基工程施工与设计建立起统一的质量标准,确保桩基工程施工质量达到设计要求成为可能。

Existence of present problems in quality qualifying control of pile foundation engineering is studied firstly, and then probability theory, deducing method on random sample and novel technique of dynamic testing for pile foundation are quoted. To propose the random model of quality qualifying control-reliability method in pile foundation engineering, to ensure the unitize theory question for model of quality qualifying control in pile foundation engineering and reliability method in structure design obtain solving. In practice, unitive quality criterion for construction and design in pile foundation engineering were established, to ensure the quality of construction in pile foundation to meet requirement of design could be possible.
