Comprehensive Analysis of Collapsible Loess

Loess is a kind of special sediment with pore structure and rich carbonate in its composition. Due to the characteristics composition, most loess has collapsibility. There are resources distributed northwest area China. With improvement traffic network west area, use as roadbed gradually increasing. Therefore, during construction process, engineering problems encountered by also increased, which seriously hindered process network. Most our country collapsible loess. So common problem how dispose collapsibility loess.In this paper, evaluation indexes summarized studied, mechanism further explored, three methods treatment summarized, will provide guidance for future areas.
