山西吕梁民用机场抗剪强度指标分析与探讨

On analysis and exploration for shear strength index at Lvliang Civil Airport of Shanxi

结合拟建工程的大面积挖填方,针对场地内主要分布的马兰黄土和离石黄土,分别采取土样进行击实试验,压缩和固结剪切试验,探讨了抗剪强度与含水量的变化规律,为地基填方和边坡设计提供了可靠的参数。

Combining with the large area excavation and filling of the planning building construction,the paper adopts the compaction tests,the compression and consolidated shear tests on the soil samples of the main Malan Loess and Lishi Loess in the field,and explores the change rule for the shear strength and the water content,so as to provide the reliable parameter for the foundation filling and the slope design.
