摘要：
The freeze-thaw circulating water and soil are the two important factors of soil compression strength The study based on Different moisture content and freeze-thaw cycles, In order to study the influence of freeze-thaw cycles on the damage characteristics of loess with different moisture content of the loess. Take samples from Shanxi Yangqu No. 1 tunnel face as the research object. Do unconfined compressive strength test on condition of different moisture content and different freeze-thaw cycles, analysis the effect of moisture content and The freeze-thaw cycle on unsaturated loess strength damage, and has carried on the fitting formula. The results is same soil moisture content under the freeze-thaw cycle of experience, the uniaxial compressive strength decreased with the times of freezing and thawing cycles. Hope this paper can provide construction reference in loess distributed area of yangqu even in shanxi.
