迁安灰黑色粘性土工程特性评价及工程应用

Engineering Character Evaluation and Application of Grey and Black Cohesive Soil in Qian′an District

该文通过大量的试验数据对唐山迁安地区的灰黑色粘性土工程特性进行了评价,分析了灰黑色粘性土的工程地质条件和有机质含量、击实参数等各项特性指标,测定了灰黑色粘性土掺砂前后和回填前后的含水率变化过程及相应力学指标,并进行了对比验证,力求通过最优含水率找到掺砂混合土的最佳夯实状态,从而为类似工程的应用提供一种可以借鉴的方法。

Through many test data of engineering characteristics on grey and black cohesive soil an evaluation is made. And its engineering geology conditions and organic content and hammering parameters and so on characteristics index before and after are analyzed. The water content and relative mechanical index of grey and black cohesive soil adding sand and back filling are measured and their comparison check are conducted in order to find out the most optimal status of hammering soil with optimal water content. Thus a reference technique for similar project can be used.
