针对膨胀土路基的改良问题,进行了一系列室内土工试验,对石灰以及石灰改良后膨胀土的基本物理性质、胀缩特性、击实特性、力学特性等进行了室内对比试验分析,结果表明,石灰改良膨胀土试样的强度主要取决于试样的含水率、掺灰率.
針對膨脹土路基的改良問題,進行瞭一繫列室內土工試驗,對石灰以及石灰改良後膨脹土的基本物理性質、脹縮特性、擊實特性、力學特性等進行瞭室內對比試驗分析,結果錶明,石灰改良膨脹土試樣的彊度主要取決于試樣的含水率、摻灰率.

A laboratory testing program was conducted as improver aimed at the swell-shrink characteristics of the roadbed. The basic physical properties, exponsion features, compaction properties and mechanical properties were analyzed. The results of the study show that the strength of the mixture is highly dependent on the water content and lime content at compaction.
