Preliminary Study on In-Situ Test for Testing Operation Error for Shear Wave Velocity at Class III Site

[摘要] A special in-situ test for shear wave velocity at class III site is conducted in the given borehole by three professional groups using the same suspension logging apparatus. Testing operation error for shear wave velocity and its effect on ground motion with different intensity are investigated. The main conclusions are as follows: (1) the testing operation error for shear wave velocity exists objectively. The testing data in this paper indicate the error is independent on burying depth and the maximum value of error is less than 20%; (2) when the amplitude of input acceleration is not more than 0.2g, the effect for testing operation error on ground motion can be ignored. However, when the input acceleration is larger, this effect becomes larger and should be recognized and examined carefully.
