【摘要】:在深厚軟土地基條件下,背水坡閉氣土方填筑對樁基框架結(jié)構(gòu)堤防的受力、變形將產(chǎn)生較大影響。為分析上述影響的規(guī)律性,結(jié)合溫州市某海堤工程實例,以實際工況為條件,采用Midas NX有限元軟件,分析了板樁、密排灌注樁及攪拌樁地基處理后樁基框架結(jié)構(gòu)堤防的變形特點。結(jié)果表明:水泥攪拌樁地基處理效果最好。進一步分析了不同攪拌樁樁長和樁間距的處理效果,探討了攪拌樁的最優(yōu)配置。
[Abstract]:Under the condition of deep soft soil foundation, the stress and deformation of the pile foundation frame structure embankment will be greatly affected by the closed earth filling on the back water slope. In order to analyze the regularity of the above effects, combined with an example of a seawall project in Wenzhou City, the sheet pile was analyzed by using Midas NX finite element software under actual working conditions. Deformation characteristics of embankment of frame structure of pile foundation after treatment of compacted cast-in-place pile and mixing pile foundation. The results show that the treatment effect of cement mixing pile foundation is the best. Furthermore, the treatment effect of different mixing pile length and pile spacing is analyzed, and the optimal arrangement of mixing pile is discussed.
