| 摘 要： | 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。

| Abstract: | Based on the hypothisis of elastic two-layered foundation system under infinite slab with know values of thickneses and slab modulus,a bak analysis program ADMODE for evaluating foundation moduli is worked out by putting the back analysis idea into an optimization problem,included the verifying subprogram compiled according to the hypothisis of finite slab resting on elastic two-layered system foundation.The validities of the theory and pro- gram have been checked and verified by laboratory tests.Besides,the founda- tion moduli have also been computed using the data obtained from Tai Zhou experimental road with the program presented.Through regression analysis, the empirical formulas for computing the increasing multiples of the moduli of subgrade and course are derived. |
