Abstract

Abstract: The paper analyses and studies the plasticity index,compaction,maximum dry density and optimum moisture content of the expansive soil in Longquanyi in Chengdu as well as the swelling pressure-moisture content, swelling pressure-dry density and effective cohesion-moisture content relationships,and discusses the effects of four stabilizing materiats: lime cement,lime,SBT as well as STX no the improvement of the optimum moisture content,unconfined compression strength,expansion rate and so on

Key words: expansive soil, swelling pressure, expansion rate, unconfined compression strength

摘要： 分析研究了成都龙泉驿地区膨胀土的界限含水量、最大干密度、最佳含水量以及膨胀力-干密度、膨胀力-含水量、有效粘聚力-含水量等之间的关系,探讨了4种固化剂改良方法———石灰、水泥石灰、SBT及STX对改善膨胀土最佳含水量、无侧限抗压强度及膨胀率等的影响.

关键词: 膨胀土, 膨胀力, 膨胀率, 无侧限抗压强度
