以稻草和麦秸秆加筋滨海盐渍土,可提高土的强度和抗变形能力。使用SH胶对稻草和麦秸秆进行防腐处理,完成了防腐前后的吸水实验和极限拉伸实验。对比实验结果得知:1天然和浸胶稻草的吸水率均比麦秸秆的大;2浸胶提高了稻草与麦秸秆的极限拉力和极限延伸率;3浸胶稻草的吸水率的降低率、极限延伸率的增长率和极限拉力的增长率均低于浸胶麦秸秆的;4天然、浸海水、浸胶、浸胶后再浸海水稻草的极限延伸率和极限拉力均高于相应麦秸秆的。稻草和麦秸秆均适宜作加筋材料使用。应用在加筋土中,稻草比麦秸秆具有更良好的抗拉性能及协调土的变形能力。在浸胶后的防腐效果及其增强抗拉性能上,麦秸秆优于稻草。
Reinforced coastal saline soil with straw and wheat straw can improve soil strength and resistance to deformation. The use of SH plastic straw and wheat straw preservative treatment, the completion of the anti-corrosion before and after the water absorption test and ultimate tensile test. The results of the comparative experiments showed that: 1 the water absorption of natural and digestible straw was higher than that of straw; 2 the dipped straw increased the ultimate tensile and ultimate elongation of straw and wheat straw; 3 the rate of decrease of water absorption of straw and straw, The rate of ultimate elongation and the rate of increase of ultimate tensile force were lower than those of straw wheat straw. 4 The ultimate elongation and ultimate tensile strength of natural, immersed seawater, dipped and dipped soaked straw were higher than those of corresponding straw of. Straw and wheat straw are suitable for use as reinforcement material. Used in reinforced soil, straw has better tensile properties than wheat straw and coordinates soil deformability. In dipped antiseptic effect and its enhanced tensile properties, wheat straw is better than straw.
