摘要
基桩静载测试得到的荷载-位移曲线是对其承载性能进行评估的主要依据,本文采用Visual Basic平台开发基桩静载数据常规处理与可靠性分析软件。该软件可绘制单根基桩的荷载-位移、位移-时间对数和位移-荷载对数曲线。在组集特定建筑物下多根单桩荷载-位移检测数据的基础上,可展示基桩承载能力的总体评估成果,如平均安全系数、可靠度指标。该软件不仅可用于静载常规数据处理,也可用于基桩承载性能几何可靠性评估报告的编制。
The load-displacement curves of foundation piles subjected to static tests are mainly used to evaluate their bearing capacity.In this study,a package for the reliability analysis and data processing is developed based on the programming platform of the Visual Basic.The curves of load vs displacement,displacement vs logarithm of time,and displacement vs logarithm of load are plotted for each pile.Once all load-displacement curves for multiple piles under a specific building are assembled,some computed results of bearing characteristics can be achieved,such as,an averaged factor of safety and a reliability index.The software can be used not only for routine data processing of static load tests,but also for a preparation of geometric reliability assessment reports for the bearing performance of foundation piles.
