【摘要】 边坡工程中,土体一般处于非饱和状态,将非饱和土力学理论应用于边坡稳定分析,已成为当今岩土工程研究中的一个热点。总结了非饱和土力学理论,特别是土水特征曲线的研究现状,利用土水特征曲线,建立了一个非饱和土含水量与强度的关系式,并用来对粤赣高速公路残积土高边坡进行了稳定分析。揭示了土体含水量在高边坡稳定分析中的重要作用,提出把含水量作为边坡稳定分析的一个重要参数,该计算分析思想在高速公路高边坡设计和施工中具有广泛的参考价值。更多还原

【Abstract】 Soils in slope engineering are commonly at unsaturated state.The applications of unsaturated soil mechanics in slope stabilities analysis becomes a hotspot in geotechnical researches.The states of arts on unsaturated soil mechanics especially on the soil-water characteristics curve(SWCC) are summarized.A formula is put forward to describe the relationship between water content and strength of unsaturated soils.The formula is applied in the stability analysis of a residual soil slope in Yue-Gan Expressway.The water content of the soil is verified to be very important for slope stability and it is suggested to be a necessary parameter for slope stabilities analysis.The caculation and analysis methods may be widely refered in the design and construction of highway slope.更多还原
