宁波软土地区基准基床系数试验方法与取值标准研究

A study of the test method and value standard of the modulus of reference subgrade reaction in the Ningbo soft soil area

以宁波栎社机场岩土工程勘察项目为依托,采用现场原位测试与室内试验相结合的方法,对不同状态下(流塑、可塑、软塑)的土体基床系数进行测试分析。根据测试成果存在的差异性,对原位测试与室内试验的测试原理、方法、影响因素进行分析,依据相关理论,提出适合宁波软土地区基准基床系数的原位测试、室内试验方法和取值公式。

Relying on the geotechnical engineering investigation in the Lishe Airport,Ningbo city,the modulus of reference subgrade reaction under the different conditions（ plastic flow,plastic,soft plastic） is analyzed through the method of combining the situ testing and the indoor test. According to the difference of the test results,the principle,method and influence factor of the test in situ and laboratory test are analyzed. Finally relating the correlation theory,the method of the situ testing,indoor test and the value formula which is suited for the Ningbo soft soil area is advanced.
