摘要：

In order to analyse the bearing mechanism of mudstone with soft-hard alternant strata, the mudstone layer is choosed, and the interbedded mudstone models were built. The standard penetration test and shallow plate loading test have been studied. The results of test show that the relationship between standard penetration number and depth of burial is exponential relationship. The characteristic value of bearing capacity of interbedded mudstone is linearly related to the logarithm of standard penetration number. The bearing characteristic of interbedded mudstone is vulnerable to the unloading, disturbance and water content. Model formula of the relationship between the characteristic value of bearing capacity and the logarithm of blow count was verified with high reliability.
