土的组成、结构与固化技术
摘要:在对土的组成及其结构进行深入分析的基础上,认为土固化基本原理就是强化土颗粒间结构连结,改善颗粒接触,提出由化学作用而形成的同相接触是提高粘土体系强度的关键技术,并总结了土固化的几个重要技术途径。对目前采用最多的土固化方法——土壤固化剂法进行了分析,对几类土壤固化剂及其机理进行了阐述。对固化土收缩开裂、水稳定性和抗冻性等几个影响固化土耐久性的主要因素进行了分析探讨。
Abstract:On the base of having given a deep analysis on composition and structure of soil,drawing a conclusion that the principle of soil stabilization is enhancing the strength of joints among soil particles and improving the contact of soil particles, proposing that the key technology of increasing the soil strength is chemical reaction occurring between bonding materials and soil particles.And summarizing some important technical methods of soil consolidation.Moreover analyzing the method of soil consolidation agent which is often used at present in soil stabilization and probing into some kinds of soil consolidation agents.At last,analyzing some important factors that influence the stabilizing soil durability such as shrinkage,water resistance,freeze-thaw durability.
