以防腐后的麦秸秆和石灰加筋固化滨海盐渍土,解决由盐渍土的盐胀和溶陷引起的低强度和大变形问题.将布筋区域设计为上半部、中部、下半部、上部1/3与下部1/3处分别布筋,共5种布筋区域;将麦秸秆切割成圆管状、半圆管状、1/4圆管状、圆管碾压后的随机形状,共4种加筋横截面形状.加筋盐渍土和加筋石灰盐渍土的三轴 UU 抗剪强度表明,适宜的布筋区域均为下半部,适宜的加筋横截面形状均为1/4圆管状.麦秸秆的布筋区域和加筋横截面形状对加筋盐渍土和加筋石灰土的抗剪强度均具有明显影响.加筋可有效地提高黏聚力,但对内摩擦角影响较小.麦秸秆适宜作加筋材料,5种布筋区域和4种麦秸秆截面形状的加筋条件下,均可提高滨海盐渍土的抗剪强度和抗变形性能.

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.
