摘要：Combined with the Dingxi-Lintao Expressway, this paper discusses the method of strengthening the collapsible loess foundation, and conducts the indoor California Bearing Ratio (CBR) test research according to the characteristics of the highway project. Under the optimal water content, through the comparison analysis of the test results of the plain soil California Bearing Ratio test and the lime soil California Bearing Ratio test after the ash mixing ratio reaches 5%, it can be found that under the condition that the compaction degree reaches 96%, the test result after ash mixing is 5% The CBR value of this kind has been greatly improved, and the expansion amount has been drastically reduced. It is proved that this treatment method can eliminate the adverse effects of collapsible loess, significantly increase the bearing capacity of the foundation, and provide good guidance for the subsequent roadbed treatment design and construction.
