復(fù)雜應(yīng)力條件下重塑黏土水力-力學(xué)行為多尺度研究 內(nèi)容簡介

本書介紹了復(fù)雜應(yīng)力條件下重塑黏土水力-力學(xué)行為相關(guān)試驗研究成果。研究對象主要為兩種黏土,即高嶺土和粉質(zhì)黏土(高嶺土和石英砂的混合物)。本書共包括8個章節(jié)。第1章主要介紹了重塑黏土的研究背景及國內(nèi)外相關(guān)研究現(xiàn)狀。第2章通過三軸試驗研究了超固結(jié)比、應(yīng)力路徑和應(yīng)力水平對飽和重塑黏土宏觀力學(xué)行為尤其是剪脹性的影響規(guī)律。第3章借助掃描電鏡表征了三軸加載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加載作用下重塑黏土微觀孔隙結(jié)構(gòu)和微裂隙的發(fā)展規(guī)律。第5章考慮微觀孔隙率和孔徑分布特征建立了重塑黏土的滲透模型。第6章開發(fā)一種新型非飽和三軸試驗系統(tǒng),據(jù)此研究了干化路徑下非飽和重塑黏土的力學(xué)行為。第7章結(jié)合滲透試驗、壓力板試驗和微觀試驗研究了壓實粉質(zhì)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(zhì)黏土的抗剪強度特性和微觀結(jié)構(gòu)演變規(guī)律。本書成果有助于深入認(rèn)識復(fù)雜應(yīng)力條件下重塑黏土的水力-力學(xué)行為及其本質(zhì),并為與重塑黏土相關(guān)的工程建設(shè)提供有益指導(dǎo)。
