Test and Research on Rheology Dynamic Characteristics of Marine Deposit Soft Soil under Dynamic Loading in Xiamen

摘要

Indicated by the practical investigating and theoretic analysis, the rheologic action of the soft soil could be accelerated by earthquake the dynamic loading, which induces more geotechnical engineering accidents and geologic disasters, for example foundation sedimentation and sliding movement, the project destabilizing to collapse etc. The samples of marine deposit soft soil are collected in xiamen, and the rheologic rate, rheologic acceleration and rheologic strain under the dynamic loading of sinusoidal variation are tested and analyzed using dynamic-triaxial device, and the influences of dynamic loading frequency and breadth to dynamic Characteristics of soft soil are contrasted and analyzed. The research results have important academic signification and actual signification for us to search after rheologic dynamic characteristic of soft soil, open out the rheologic dynamic mechanism of bursting out fearful geotechnical engineering accidents and geologic disasters under dynamic loading.
