岩土工程勘察中剪切波速的应用
Application of shear wave velocity in geotechnical engineering investigation
为了较准确地确定地基基础方案，本文采用剪切波速方法。依据对江西省共青城南湖区新建大学城进行的岩土工程勘察，对当地进行场地土层刚度（剪切波速）的测试，进而确定建筑的场地类别。单桩竖向承载力特征值应以单桩垂直静载荷试验确定，采用群桩承台设计时应考虑群桩承台效应。合理的运用剪切波速的测试，可以较准确地确定地基方案。
The scheme determination of foundation by field experiment to be sure, in order to accurately determine the scheme, based on the shear wave velocity method. Basis of komsomolsk jiangxi province south lake area new town of geotechnical engineering, the local field soil stiffness) (shear wave velocity test, collecting data through the three waveform record. By communication with computer, and transmit data from the instrument to the computer, the shear wave velocity of soil is obtained after processing, in turn, determine the type of construction field, the result is a characteristic value should be with single pile vertical bearing capacity of the single pile vertical static load test to determine, the number of piles in the same conditions of not less than 1% of the total, and not less than three, the group should be considered in the design of pile caps group effect of pile caps. Therefore, reasonable use of shear wave velocity test, can accurately determine the foundation plan.
