本文译自苏联1980年出版的《公路水泥混凝土面层》一书的第五章第五节。文章以P彼立契和B.A.契尔年柯夫提出的图式为基础,将水泥混凝土面层的纵向稳定性计算归纳为六种计算图式进行理论分析并提出各类图式的计算公式和适用范围;文章还就面层纵向稳定性和胀缝问距计算关系进行了理论和实践的探讨,提出了胀缝间距计算公式及当今世界各国对胀缝设置的情况。文章内容切合实际,阐述透彻,特别是关于设置胀缝问题讲得较为详细,有参考价值。
This article is translated from the Soviet Union, published in 1980, “Highway Cement Concrete Surface,” a book Chapter V of the fifth section. Based on the drawings proposed by P Petlych and BA Chernykov, the paper summarizes the longitudinal stability of cement concrete surface layer into six kinds of calculation patterns and makes theoretical analysis and puts forward the formulas of various kinds of formulas and The paper also discusses the relationship between the vertical stability of the surface layer and the calculation of the distance between the expansion joints and the theory and practice. The calculation formula of the expansion joints and the setting of the expansion joints in all countries are put forward. The content of the article is realistic, elaborate thorough, especially on the issue of setting up the expansion joints speak in more detail, a reference value.
