本文主要研究了昔格达地层用作大面积高填方地基填料的适应性。通过大量的室内及现场试验,确定了昔格达组土岩单料及混合料最大干密度和最佳含水率,并经过现场填筑工艺试验确定了最优的松铺厚度、最佳的碾压遍数、最好的碾压方式、最适合的压实机械等。结合攀西新基地场地工程实例进行了分析论述,对攀西地区的大型工程具有重要的指导意义和借鉴价值。
This paper mainly studies the suitability of the Xigeda strata for the packing of large area and high fill. Through a large number of indoor and field tests, the maximum dry density and the optimum moisture content of the earth and rock materials and mixtures in the Xigeda Group were determined, and the optimum thickness of the loose layer was determined through field filling test. The best rolling The number of times, the best rolling method, the most suitable compaction machinery. Combining with the Panxi new base site project examples were analyzed and discussed on the large-scale projects in Panxi region has an important guiding significance and reference value.
