The drainage network leakage of existing building led the humidity of the soil formation to increase. In order to solve the instability conditions of loess slope engineering which was caused by the increasing humidity of the soil formation, the appropriate treatment measures through the slope stability analysis were proposed.Keywords: unsaturated soil; pipeline leakage; loess slope; slope stability analysis*陜西省重點(diǎn)學(xué)科資助項(xiàng)目(E01002)。作者簡介:韓曉雷,博士,教授,Email:hanxlyt@xauat.edu.cn。參考文獻(xiàn)[1]王永焱,林在貫. 中國黃土的結(jié)構(gòu)特征及物理力學(xué)性質(zhì)[M].北京:科學(xué)出版社,1990.[2]謝定義. 黃土力學(xué)特性與應(yīng)用研究的過去、現(xiàn)在與未來[J].地下空間,1999,19(4):273285.[3]張克恭,劉松玉.土力學(xué)[M].北京:中國建筑工業(yè)出版社,2001.[4]GB50330—2002建筑邊坡工程技術(shù)規(guī)范[S]. 北京: 中國建筑工業(yè)出版社,2002.
