| Abstract: | 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 pore pressure hardening curve growth of the laterite are described. The dynamic pore pressure model put forward by Mr Zhang Jianming is depended on to analyze the laterite in Haikou and get the model parameters. |
