    本書介紹了複雜應力條件下重塑黏土水力-力學行為相關試驗研究成果。研究對象主要為兩種黏土,即高嶺土和粉質黏土(高嶺土和石英砂的混合物)。本書共包括8個章節。第1章主要介紹了重塑黏土的研究背景及國內外相關研究現狀。第2章通過三軸試驗研究了超固結比、應力路徑和應力水平對飽和重塑黏土宏觀力學行為尤其是剪脹性的影響規律。第3章借助掃描電鏡表徵了三軸載入作用下重塑黏土顆粒重新排列及演變特性。第4章通過掃描電鏡、壓汞儀和顯微CT成像等微觀試驗分析了三軸載入作用下重塑黏土微觀孔隙結構和微裂隙的發展規律。第5章考慮微觀孔隙率和孔徑分佈特徵建立了重塑黏土的滲透模型。第6章開發一種新型非飽和三軸試驗系統,據此研究了干化路徑下非飽和重塑黏土的力學行為。第7章結合滲透試驗、壓力板試驗和微觀試驗研究了壓實粉質黏土的滲透特性、持水特性及其微觀機理。第8章通過非飽和三軸試驗和微觀試驗,分析了濕化路徑下非飽和壓實粉質黏土的抗剪強度特性和微觀結構演變規律。本書成果有助於深入認識複雜應力條件下重塑黏土的水力-力學行為及其本質,併為與重塑黏土相關的工程建設提供有益指導。
