本文根据西安市第三建筑工程公司十年来积累的204项工程素土和158项工程灰土的室内击实试验资料,并收集了20项工程近8000个填土密实度测定数据,运用数理统计方法进行了分析。根据分析所得的结论,探讨了西安地区在执行现行有关规范规定的填土夯实质量指标方面存在的问题,并根据上述资料统计结果,分别提出了西安地区素土和灰土垫层按压实系数D_y或干容重γ_d控制时的具体建议值,可供有关设计施工单位参考。

In this paper, according to the indoor compaction test data of 204 engineering plain soils and 158 engineering lime soils accumulated by Xi’an No. 3 Construction Engineering Company in the past ten years, data of nearly 8,000 filling compaction degrees of 20 projects were collected, and mathematical statistics methods were used. Analyzed. Based on the conclusions of the analysis, the problems existing in the Xi’an region in the implementation of the relevant provisions of the current specifications of the quality of filling compaction are discussed. Based on the statistical results of the above data, the compaction coefficient D_y of the soil and ash soil cushions in the Xi’an region is proposed respectively. The specific recommended value when the dry bulk density γ_d is controlled can be used as a reference for relevant design and construction companies.
