[提要] 通過對某工程實例的反分析計算,提出了建立在可靠度分析基礎(chǔ)之上的深基坑樁撐支護(hù)結(jié)構(gòu)優(yōu)化設(shè)計方法。為了進(jìn)行支護(hù)結(jié)構(gòu)的可靠性設(shè)計,探討了隨機(jī)變量對支護(hù)結(jié)構(gòu)設(shè)計的影響,并給出了進(jìn)行支護(hù)結(jié)構(gòu)計算的實例。
[關(guān)鍵詞] 深基坑 樁撐支護(hù)結(jié)構(gòu) 可靠性設(shè)計Through the back-analysis of a computing example, the design optimhation of pile-strut bracing struc-
ture of deep foundation pit is presented based on reliability analysis. In order to proceeding the reliability design of bracing structure, the author suggests that random variables have an influence on the design of bracing.structure and gives a computing example.
Keywords: deep foundation pit; pile-strut bracing structrue;reliability analysis
