摘要
过去通常采用工程费用最低的评价准则来确定最优地基的处理办案,这种单因素的方案分析方法已逐渐为多因素综合分析方法所代替。文中举例了多因素分析法的具体应用。传统的地基设计采用确定性方法,而不考虑设计涉及的各个方面、各个参数的分散性、随机性和模糊性。文中提出的设计新途径是以统计概率理论为基础,比传统的设计方法更合适、更可靠。为此,应向设计新途径转轨,并努力创造必要的条件。
Optimal alternative of soil improvement is generally chosen by using the criterion of minimum construction cost.Such singlfactor alternative analysis is gradually replaced by the multifactor alternative analysis.In this paper,an illustrative example is given to show the application of the latter method.Determinisic approach is usually adopted in traditional foundation design without consideration of the scatterness,randomness or fuzziness of parameters in all aspects.It has now been shown that a new design approach which is based on statistics and probability theory is more reasonable and reliable than the traditional one.So,the necessary fundamental works should be done for putting that approach into practice.
