Study on Safety Factor of Loess Cave Dwellings with Pitted Courtyard in Different Rainfall Infiltration

Abstract:

Baishe villagers have lived in loess cave dwelling with pitted courtyard for hundreds of years in Sanyuan County of China .Rainfall infiltration badly destroyed the habitation in recent years so that the study is very important on security and stability of the loess cave dwelling. By field measurements, the sizes of local cave dwellings were mastered and variation was grasped of average annual and monthly rainfall. The physical and mechanical parameters were acquired with loess samples in different water content by the conventional and triaxial soil test. At the same time, based on the literature data, the relationship was established between rainfall and water content. Safety factor was defined for loess cave dwellings in different depths utilizing the expressions of the surrounding rock loop stress and the Mohr-Coulomb theory. The variation of stability of loess cave dwelling could be ultimately analyzed under different rainfall.
