摘要
本文简要地介绍了桩基自平衡测试的Q—S曲线向传统静载试验Q—S曲线的等效转换原理。分析了测试数据的可靠性,考虑转换方法中各参数的随机变化,得出了各参数的分布。重点探讨了从两个随机因素影响的测试数据中获得每个因素的分布的简化方法以及如何利用多次试验数据(每次试验数据的影响因素不全相同)来补充一次试验得到的样本数据较少(本文为2个)的统计方法。最后分析了桩基自平衡测试方法的可靠性。
In this paper, the equivalent conversion principle from self-balanced Q-S curve to traditional Q-S curve on pile head is introduced simply. Reliability of test data is analyzed and randomization of each parameter is considered. Distribution of each parameter is obtained. Particularly, the method how to obtain distribution of every factor from the test data which are affected by two random factors and the statistical method how to use test data obtained in different times (influencing factors of each time are different) to perfect the scanty stylebook (two data in this paper) are discussed. Reliability of self- balanced test method is analyzed at last.
