| 摘 要： | 江西某厂填筑地基时,未清理处于填土与基础之间的淤泥,导致工程灾害发生。作者研究表明,由于排水通道不畅,位于基础与填土间的淤泥质粉质粘土固结作用缓慢,在地下水渗流及地表水浸泡下发生水化作用,外荷载增加及频繁的涨退水是导致不稳定边坡产生工程灾害的诱发因素。治理方法研究表明,利用低压注浆法固化滑动面及增加地基抗剪能力是防治工程灾害较好方法,结合其他方法,低压注浆法可以根治滑坡。施工结果经试用表明达到预期目的。本文提供的理论及施工方法,可以在类似工程中应用,这点已在西部某工程中得到证实。

| Abstract: | The silt between basis and covered layer was not cleared away every inch in the building of civilian field of a factory in Jiangxi and it had resulted in engineering accident.This study showed: that the solidification of silt between basis and covered layer developed slowly because passageway of drainage was not clear;that hydration of the silt occurred because of leakage of ground water along the sliding band and immersion of the lake water;that increasing of load and frequent ascending and descending of the lake water level were the inducement of engineering accident of unstable slope.The methods of controlling slip were suggested: low-pressure-inject-slurry was suitable for protecting-controlling of slip and it could solid sliding band and increase capacity against shearing force to control slip with other methods throughout.Probation of the engineering testified that the result was satisfied.The method of theory and engineering might be applied to protecting and controlling of the similar engineering accident and it is certified by the engineering further in the Western China in August,2003. |
