摘要
为了研究交变载荷对负压筒型基础地基稳定性的影响,利用物理模型实验模拟现场及MATLAB编程,通过应力模型计算和极限状态分析,即抗剪强度和剪切应力曲线的关系直观看出了地基在传感器处的稳定性,借助极限稳定状态下的极限有效应力确定出了物模实验中的每次实验所反映的现场地基稳定性情况。
In order to study on alternated load influences on negative cylinder foundation stability,simulating site with physical model test and MATLAB program,through stress model calculation and limit situation analysis, i.e.looked foundation stability in end instrument site from shear intensity and shearing stress curve relation directly,the site foundation stability situation reflected from physical model test every test was determined with limit effective stress in limit stable situation.
