Research on Carrying Capacity of Sandy Backwall of Solar Greenhouses in Non-cultivated Land in Alax
摘要
Abstract
For ensuring the bearing capacity of the sandy soil using in back wall of solar greenhouse in non -cultivated land in alashan with shear test and unconfined compression test though orthogonal test .Compute and analyse the actual bearing capacity that the back wall of solar greenhouses need and seek out a combination which can guarantee safty and -can cost less .The result shows that shear strength and compressive strength increase along with cement and soil stabiliz -er; the proportion of cement from 1%to 3%improve most performance ,internal friction angle raises more than 20%and cohesion raises more than 60% and unconfined compression promotes more than 76 .09%;the soil with 3%cement and 1%soil stabilizer can reaches the requirement for back wall of solar greenhouse and can get better performance .It can be a reference for construction of solar greenhouse in similar soil condition .关键词
