| 摘 要： | 在洞庭湖漫滩阶地的冲湖积淤泥质软土上,分布着一些次级牛轭湖和季节性洪道成因的极软淤积物。在荷载作用下,该软土易产生较大的压缩沉降和顺坡蠕变沉降,当其与下部软土基层共同作用时,必将加剧建筑物的沉降和倾斜。利用生石灰砂桩能起到较好的抗滑止沉作用;根据软土的触变性和流变性,利用应力解除法能有效地矫正建筑物倾斜,从而达到纠偏加固的目的。

| Abstract: | There are some softer accumulation horizon in the ox-bow lake and season river on the huge mucky soil of alluvial and lacustrine deposits in accumulation terrace around Dongting lake. In the case of load action.it would occur compressing settlement and creeping settlement,and the settlement and incline of building will be increased when it acted each other with mucky soil. According to the properties of lime and soft clay, we could effectively resist sliding and settling and rectify incline of building by using limepiles and stress relieving method,in order to reach the aim of rectification and conslolidatlon. |
