pile-on properties

基本解释

Based on the research status at home and abroad, the engineering properties and the pile settlement theory of the super-long piles are analyzed in the paper.
首先，在国内外众多学者研究工作的基础上，对超长桩工程性状特征进行了总结。同时对桩基沉降理论的国内外研究现状进行了分析。
Field tests on pile groups with prototype size have been carried out in order to study the behavior and the working properties of the cap-pile groups-soil interaction in the pile foundation.
为了研究群桩基础中承台、群桩，和土的共同作用及其工作性状，进行了与工程实际相符合的现场群桩试验，通过安设的测试仪器对承台下基土反力、桩侧摩阻力、桩端阻力等进行了测定。
On pile-soil interface, mechanics properties of contact surface are simulated by contact elements, and soil nonlinearity is simulated by DP elastic-plastic model provided by ANSYS FEM program.
对桩—土间的相互关系使用接触单元进行模拟，采用DP弹塑性模型来反映土体的本构关系。
