摘要
地震是群灾之首,而海口市是全国省会城市中设防烈度最高的城市。通过室内动三轴试验数据,分析海南区域性特殊土——红土的动力特性;选取规范法为破坏准则,分析了海口红土在各种影响因素下动孔压的特性。对超固结土孔压增长机理进行分析。描述了海口红土动孔压硬化型曲线增长的三个过程。根据张建民提出的动孔压模型,对海口红土进行分析,获得模型参数。
Earthquake is most dangerous and Haikou is the city that has highest fortification intensity among all the capital cities in the country. With indoor dynamic triaxial test data, the dynamic characteristics of the special soil, laterite, in Hainan is analyzed. Standard method is selected as failure criterion and the dynamic pore pressure characteristics of the laterite there is analyzed under various effecting factors. Moreover, mechanism of pore pressure increasing of over consolidated soil is studied and the three stages of dynamic curve growth of the laterite are described. The dynamic pore pressure model put forward is depended on to analyze the laterite in Haikou and get the model parameters. pore pressure hardening by Mr Zhang Jianming
