超软淤泥地基浅层二次真空预压效果试验研究
Experimental study on reinforcing effects of twice vacuum pre-loading of extreme-soft silt foundation
摘要
Abstract
Aiming at the extremely low bearing capacity of hydraulic fill foundation, the twice vacuum pre-loading reinforcing method, firstly preloading cushion layer without sand and then preloading cushion layer containing sand, was adopted to strength-en the silt foundation. By in-situ test, the vacuum degree and foundation settlement in the two preloading process were meas-ured. The results showed that the first preloading could effectively solve the problem of unable-to -construction caused by the extremely low foundation bearing capacity;the second preloading could improve transmission effect of vacuum pressure and fur-ther upgrade the foundation bearing capacity.关键词
