以弹性双层地基上无限大板假设为基础,在结构厚度、混凝土板的弹性模量均为已知的条件下,把基础各层模量的反算构思归结为一优化问题,编制了 ADMDDE 程序,并根据弹性双层地基上有限大板假设编制了验证子程序。通过室内试验,验证了本文假设和程序的正确性。此外,还利用台州试验路试验资料,进行模量反算,回归并分别推荐了土基和基层模量增大倍数的计算公式。
Based on the assumption of an infinite slab on an elastic double-layered foundation, under the condition that both the structural thickness and the elastic modulus of the concrete slab are known, the inverse calculations of the modulus of each underlying layer are reduced to an optimization problem, and ADMDDE is compiled. Procedures and verification subroutines were prepared based on the assumption of a finite board on an elastic double-layered foundation. Through indoor experiments, the correctness of the assumptions and procedures in this paper was verified. In addition, the test data of Taizhou Test Road was also used to calculate the modulus of back-calculation, regression, and the calculation formulas for the increase in modulus of soil-base and base-layer modulus were respectively recommended.
