Study on the Selecting Principle of Test Soil Samples in Nonlinear Seismic Response Analysis of Stratified Site

Abstract:

Soil dynamic nonlinear experimental results have significant impacts on the seismic response of engineering site, but how reasonable and effective to select soil samples for soil test, there is no good solution. Using detailed drilling velocity, density data, and rich soil test data of Shanxi Linfen Iron and Steel Hospital engineering site, four models are established and are analyzed for this problem. The results showed that: less than 3 meters of soil layer, each layer select one soil sample, for the thick soil layer, the rules of selecting one soil sample about every 3m thickness for the soil test, are recommended. If selecting one soil sample about every 5m~6m thickness for the thick soil layer, the calculation error is about ±10%.
