中文摘要 | 本文提出一新的逆分析程序以解決在大地工程逆分析時所遭遇的一些難題,如不 穩定、非唯一和共線性。這些問題可用貝氏推廣定理以綜合觀察資料及前期資料而合適地處 理。 此方法是以貝氏定理為基礎,由赤田池上所開展。逆分析的模式判定主要使用 AIC 情 報準則,也是貝氏定理的另一詮釋。本例以一觀測路堤的資料為分析。 |
英文摘要 | A new type of indirect inverse analysis procedure is proposed to overcome the difficulties the geotechnical inverse analyses are encountering (such as unstabiluity and nonuniqueness of the solutions as well as multi-collinearity). These difficulties are eased by combining the objective information (i.e. observation data) and the subjective information (i.e. the prior information) in an appropriate manner by so called extended Bayesian model proposed by Akaike. The problem of model identification in the inverse analysis is also tacked by applying well known AIC but of the Bayesian version. A case study on an embankment on soft clay is presented to illustrated the effectiveness of the new method. |
