| 摘 要： | 桩土荷载分担比是反映复合地基力学性状的重要参数。本文利用国内大型三维大型模型试验台——中国矿业大学(北京)城市地下工程相似模拟试验系统进行了8组模型试验。试验分析了荷载、桩长、褥垫层厚度、加固区土体模量对桩土荷载分担比的影响,并根据试验数据经线性回归得到桩荷载分担比的经验公式。该公式与实际工程检测数据相比较达到较高的精度,可以直接应用于工程设计。

| Abstract: | Pile-soil load share ratio is an important parameter for mechanics properties of composite foundation.8 model experiments are conducted by similar simulation experiment system of urban underground engineering in China University of Mining Technology,Beijing campus.Effect of pile-soil stress ratio by loads,pile length,cushion thickness and reinforced field modulus are studied on the basis of model experiment.This paper puts forward experience formula of pile load share ratio by multivariate linear regression on the basis of experiment data.It shows good agreement with engineering cases.So it can be applied to engineering design directly. |
