预制单桩竖向承载力可靠度分析

【摘要】 本文利用天津市区94根预制单桩的试桩资料走出单桩竖向承载力的统计参数，分析出现行天津市地基规范关于往基设计的总体可靠度，并以此为基础结出了与一定可靠指标相适应的抗力分项系数，最后与原定值设计法作了比较。更多还原

【Abstract】 Using the test data of 94 precast single piles in Tianjin area, this paper gives a statistical parameter of verti-cal bearing capacity of single piles. The standard of the integral reliability 1n the design of pile foundations in the Current Specifications of Foundations for Tianjin Area is given by back analyzing method, based on which this paPer also provides an item coefficient of the resistance corresponding to the certain reliability properties, and have a comparison finally with the deslgn method of the original values.更多还原
