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。
In this paper, a large number of test data were used to evaluate the engineering characteristics of gray-black cohesive soil in Qian’an district of Tangshan. The engineering geological conditions, organic matter content and compaction parameters of gray-black cohesive soil were analyzed. The change process of water content of clay before and after sand dredging and before and after backfilling, as well as the corresponding mechanical indexes, and verify the comparison, and strive to find the best compaction state of mixed soil with optimum moisture content, so as to provide a kind of similar engineering application Can learn from the method.
