在公路月刊上曾登载了很多城市对于道路翻浆处理的经验,这些经验都是很成熟的。现就我们在工作中的体会,提出自己的一些看法,正确与否,还请同志们提出指正和批评。一、道路翻浆的原因道路发生翻浆,大都在春秋两季,且在地下水位较高地段最易发生: (1)秋季时期:在多雨地区,由于雨水增多,气温降低,地表水蒸发有限和土壤渗透不佳,尤其是当地下水位较高时,这种现象更为严重。因此土壤含畜了大量的水份,土壤的形变模量降低,经车轮返复的压力作用,致使道路发生翻浆。 (2)春季时期:发生翻浆现象是和秋季由于地中温度坡差的水份聚积,以及冬季冰冻的影响分不开的。在秋季,由于地表水和地下水的大量供应,使土壤含水过大;至冬季,由于冰冻线的下降,使土壤中所含的水份冻结成小颗粒的冰体,在来年春季温度转高,于是土
In the monthly road magazine has published many cities on road sloughing experience, these experiences are very mature. Now, on the basis of our experience in our work, I have put forward my own views. Correctly or not, I also urge comrades to correct and criticize them. First, the cause of road dumping Threaten road, mostly in spring and autumn, and the most prone to occur in the higher groundwater level sections: (1) autumn: in rainy areas, due to increased rainfall, lower temperatures, limited evaporation of surface water and soil Poor penetration, especially when the local water table is high, is even worse. Therefore, soil contains livestock a lot of water, soil deformation modulus decreased by the pressure of the wheel to return, resulting in road dumping. (2) Spring period: The occurrence of the phenomenon of frying is inseparable from the accumulation of moisture in autumn due to the difference of temperature in the ground and the effect of winter freezing. In the autumn, due to the large supply of surface water and groundwater, soil moisture is too large. In winter, due to the decline of the freezing line, the water contained in the soil is frozen into small particles of ice body. In the coming spring, the temperature will rise, So soil
