摘要
山西汾河三坝拦河水闸取水枢纽为Ⅱ等大(2)型工程。水闸枢纽于2014年进行了除险加固,在原6孔拦河闸的基础上再向东增加2孔泄洪闸。新旧拦河泄洪闸闸基持力层为第四系全新统晚期洪冲积(Q4pal-2)浅黄、浅青灰色低液限粉土和含砂低液限粉土,结构松散,为可液化土层;通过防渗围封和水泥土搅拌桩相结合的方法对地基进行处理,不仅消除了地基液化的可能,而且加强了地基的承载能力。
The water intake junction of a sluice in Shanxi Province is an equivalent project, a large(2) sluice. In 2014, the sluice junction was reinforced, and 2 gates were added to the east on the basis of the original 6 gates. The base bearing layer of the sluice of the old and new sluices is the late Quaternary Holocene flood alluvial(Q4pal-2) light yellow/Light bluish gray silt with low liquid limit, sandy silt with low liquid limit, loose structure, liquefiable soil. After treating the foundation, the stress of the new and old sluice base is strengthened to meet the requirement of stability.
