【摘要】：針對(duì)雨天路滑這一自然現(xiàn)象,基于土力學(xué)固結(jié)理論、強(qiáng)度理論和有效應(yīng)力原理等,探討提出了簡(jiǎn)化一維等效模型條件下的建模分析方法.采用固結(jié)土體抗剪強(qiáng)度除以剪應(yīng)力的形式,建議了一種道路表面抗滑安全系數(shù).結(jié)合工程經(jīng)驗(yàn)性常見土體參數(shù)和路面行走算例,按簡(jiǎn)化模型進(jìn)行了定性和定量分析,探討了路滑的影響因素及其規(guī)律.結(jié)果表明,在算例條件下,一般砂土路面抗滑安全系數(shù)大致為黏土路面的6.0～9.0倍.土力學(xué)模型有望為路面抗滑設(shè)計(jì)和評(píng)估提供新的思路.
[Abstract]:Based on the consolidation theory of soil mechanics, strength theory and effective stress principle, a simplified one-dimensional equivalent model is proposed to analyze the natural phenomenon of road slip in rainy days. In the form of shear strength of consolidated soil divided by shear stress, a safety factor of road surface skid resistance is suggested. Combined with the common soil parameters of engineering experience and the calculation examples of pavement walking, qualitative and quantitative analysis were carried out according to the simplified model, and the influencing factors and their laws of road slip were discussed. The results show that the safety coefficient of general sand pavement is about 6.0 ~ 9.0 times of that of clay pavement. Soil mechanics model is expected to provide a new idea for pavement anti-slide design and evaluation.
