| 1. | Because the distribution of soft soil is very widely , the sliding strength of soft soil is low , the moisture content of soft soil is rich , and the compression of soft soil is large , the handling of soft base is an important problem 这是由于软土抗剪强度低,含水量大,压缩量大,路堤建成后不可避免产生不均匀沉降,影响路面平整度,这样在行车时会出现跳车现象,既不舒服,又影响安全。 |
