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

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.
