在“公路”月刊1958年10期上登载了“处理道路翻浆的计算实例”一文,笔者对其在所列举的条件下采用的计算方法有不同的看法,因此本着学习的精神,提出个人对此问题的意见,请大家指教。一、“处理道路翻浆的计算实例”一文的要点在该文的论述中,除了对春、秋两季路基土壤湿度增加的原因作了简要的说明外,对道路翻浆现象的产生着重的说明与地下水位及冰冻深度有直接关系。因此在处理翻浆道路时,也是从提高当地的冰冻线着手,并指出冰冻线应提高的数值为(参看图1,2):
In the issue of “Roads Monthly”, Issue 10, 1958, published a “Example of Calculating Road Thrust Calculations”. The author has different opinions on the calculation methods adopted under the listed conditions. Therefore, in the spirit of study, The views of this question, please advise. 1. The main points of the article “Calculation example of handling the road dumping” In the article’s discussion, except for the brief explanation of the reasons for the increase of the soil moisture in the roadbed in spring and autumn, the explanation of the road dumping phenomenon Groundwater level and the depth of the ice has a direct relationship. Therefore, when dealing with the dumping road, it is also starting from the improvement of the local freezing line, and points out that the frozen line should be increased in value (see figures 1 and 2):
