四川盆地软基分区及参数范围值统计研究

为探讨四川盆地的各主要区域软基参数值，以四川盆地12条高速公路为研究对象，根据四川盆地内的地形地貌、母岩岩性、排水条件，进行地质分区；在对应区域内进行试验数据的统计，提出推荐值。研究结果表明:随着贯入阻力 PS 的增大，软土软弱程度逐渐减小，这与理论分析和工程实践相吻合，说明试验方法和数据正确，统计规律可靠。

Statistical Study on Subarea and Parameter Range of Soft Foundation in Sichuan Basin

In order to explore soft foundation parameter of principal zones in Sichuan Basin，12 highways there are taken as the studying object.According to the landform，parent rock’s lithologic characters and drainage conditions，the Basin is zoned geologically；and then the statistics of test data is carried out in connection to corresponding zone and recommended values are proposed.The study result shows that as the increase of penetration resistance PS ，weak degree of soft soil decreases gradually，coinciding with the theoretical analysis and engineering practice and demonstrating the test method and data is correct and statistical law is reliable.
