粗粒料浸水变形分析方法的改进

 首先分析单线法、双线法各自的优点和缺点，提出试验方面用单线法试验结果修正双线法试验结果，但计算方面仍用双线法计算的思路。其次进行粗粒料大三轴单线法和双线法湿化变形试验，对浸水变形特性进行研究，发现单线法和双线法试验结果之间的一些规律，并引用其他学者的试验结果进行验证，同样成立；同时，对该规律的机制进行探讨；基于该规律，提出一个改进的浸水变形分析方法。最后分别用改进方法和双线法对试验结果进行预测，预测结果表明，改进方法计算结果和试验结果更加吻合。

IMPROVEMENT OF WETTING DEFORMATION ANALYSIS METHOD OF COARSE-GRAINED MATERIALS

The advantages and disadvantages of single-line method and double-line method for determining wetting deformation of coarse-grained materials are analyzed. The idea of combining single-line method test with double-line method to solve wetting deformation problem is presented. The wetting deformation tests of coarse- grained materials are carried out on the single-line method and double-line method by use of large triaxial test apparatus. Some laws of the test results between the single-line method and the double-line method are found by studying the wetting deformation characteristics. The test results by other scholars also verify these laws. The mechanism of these laws is discussed. Based on these laws,an improvement analysis method for determining wetting deformation is presented. Finally using improvement method and double-line method to predict the result of the experiment;the predicative results show that the improvement method is much better than the double-line method. The calculated results of the improvement method are quite agree with the test results.
