内容简介
本书介绍了复杂应力条件下重塑黏土水力-力学行为相关试验研究成果。研究对象主要为两种黏土，即高岭土和粉质黏土（高岭土和石英砂的混合物）。本书共包括8个章节。第1章主要介绍了重塑黏土的研究背景及国内外相关研究现状。第2章通过三轴试验研究了超固结比、应力路径和应力水平对饱和重塑黏土宏观力学行为尤其是剪胀性的影响规律。第3章借助扫描电镜表征了三轴加载作用下重塑黏土颗粒重新排列及演变特性。第4章通过扫描电镜、压汞仪和显微CT成像等微观试验分析了三轴加载作用下重塑黏土微观孔隙结构和微裂隙的发展规律。第5章考虑微观孔隙率和孔径分布特征建立了重塑黏土的渗透模型。第6章开发一种新型非饱和三轴试验系统，据此研究了干化路径下非饱和重塑黏土的力学行为。第7章结合渗透试验、压力板试验和微观试验研究了压实粉质黏土的渗透特性、持水特性及其微观机理。第8章通过非饱和三轴试验和微观试验，分析了湿化路径下非饱和压实粉质黏土的抗剪强度特性和微观结构演变规律。本书成果有助于深入认识复杂应力条件下重塑黏土的水力-力学行为及其本质，并为与重塑黏土相关的工程建设提供有益指导。
