麦秸秆布筋区域与截面形状下的加筋土抗剪强度
Effect of reinforcing range and cross section of wheat straw on shear strength of reinforced soil
摘要
Abstract
Saline soil may be treated with anticorrosion-wheat straw and lime for changing the properties of lesser strength and more serious deformation resulted from salt swelling and dissolved subside. Reinforcing range of specimen is in upper, middle, lower, and 1/3 section in the top and the bottom of specimen, and the cross section of wheat straw is of roundness, arch, quarter, any rolled size, which is five ranges. It has been proved that the lower reinforcing range and a quarter of cross section of wheat straw is suitable by means of triaxial shear test(UU) on reinforced saline soil with wheat straw and reinforced lime-soil with wheat straw. The reinforcing range and cross section of wheat straw effect greatly strength of saline soil with lime and wheat straw. The reinforcing contributes to cohesion of soil largely, and internal friction angle hardly, which have proved that wheat straw is feasible for reinforcing saline soil, and five reinforcing ranges in specimen and four cross sections of wheat straw always increase the shear strength and anti-deformation of saline soil.关键词
