本文在调查分析国内外有关刚性路面下基础刚度指标及其取值方法的基础上,确定用弹性模量作为基础的刚度指标。并通过铺筑试验路的方法,在各类基础的顶面和相应的路面板顶面进行了大量的载荷试验。经对试验资料的汇总,整理和分析,提出了设计路面时,基础弹性模量的计算公式。
Based on the investigation and analysis of the basic stiffness index and its value method under rigid pavement at home and abroad, this paper determines the stiffness index based on the elastic modulus. And by paving the test road approach, a large number of load tests were conducted on the top of various foundations and on the top of corresponding pavement slabs. After compiling, sorting and analyzing the test data, the formula of calculating the basic elastic modulus is put forward when designing the pavement.
