Analysis of Foundation Pit Accidents due to Expansive Soil in Hefei District

Article Preview

Abstract:

Expansive soil has the characteristics of strong swell-shrink, developing fissures and over consolidation. This kind of soil soaking into water, which leads to its volume expansion, strength reduction but compressibility decreasing make its engineering geology properties worsen. The distribution of expansive soil in Hefei is very wide, there are more pit accidents in Hefei district in recent years. Causing the accident is mainly due to the ignorance of the characteristics and damage of expansive soil. According to many years engaged in related working experience, this paper analyses two common types of damage in foundation pit accidents. Finally, throughout the analysis of several accidents, corresponding prevention measures and construction improvement scheme have been put forward.
