摘　　要：某电站厂房边坡由于前期勘探遗漏,厂房边坡开挖至距离厂房基础面20m时,发现厂房边坡整体夹有大范围的炭质泥岩且地下水丰富,炭质泥岩厚度达50m,该碳质泥岩属于软岩,在开挖揭露后遇水软化,造成厂房边坡两次塌方,同时对厂房主体结构、工期均产生重要影响。通过现场查勘以及召开专家咨询会进行讨论,采取在厂房边坡增加抗滑桩及连系梁、厂房基础灌注桩及支撑梁施工措施,确保了边坡稳定、施工工期及永久运行期的结构安全。Due to previous exploration omissions,the slope of a power plant was excavated to a distance of 20 meters from the foundation surface.It was found that the entire slope of the plant was mixed with a large area of carbonaceous mudstone and abundant groundwater.The thickness of carbonaceous mudstone is up to 50m,which belongs to soft rock.After excavation and exposure,it softened when exposed to water,causing two collapses of the factory slope and having a significant impact on the main structure and construction period of the factory.Through on-site investigation and expert consultation meetings,measures were taken to increase anti slip piles and connecting beams on the slope of the factory building,as well as to install foundation cast-in-place piles and support beams.This ensured the stability of the slope,the construction period,and the structural safety during the permanent operation period.
