以深圳市龙岗区某综合管廊工程为研究对象,采用钻探结合跨孔弹性波CT和微动法,查明岩溶发育情况,通过数学统计方法,从岩溶的发育形态、规模、充填情况、空间分布特征等方面对岩溶发育特征进行研究.研究发现,在拟建综合管廊洞身范围内及结构底板下岩溶强烈发育,主要为浅覆盖型,且以大型溶洞为主,大部分溶洞无充填.鉴于岩溶的空间分布与发育特征,结合综合管廊隧道结构的埋置深度与高程分布,本文提出了针对性的处理措施建议,旨在确保拟建综合管廊隧道结构的安全与稳定.
Study on Karst Development Characteristics of a Comprehensive Pipe Gallery Project in Shenzhen
Taking a comprehensive pipe gallery project in Longgang District of Shenzhen as the research object,the karst development situa-tion was identified by drilling combined with cross-hole elastic wave CT and micro-motion method.Through mathematical statistical methods,the karst development characteristics were studied from the aspects of karst development form,scale,filling situation and spatial distribution characteristics.The study found that the karst is strongly developed within the scope of the proposed utility tunnel and under the structural floor,which is mainly shallow cover type,and is dominated by large karst caves,most of which are not filled.In view of the spatial distribution and development characteristics of karst,combined with the buried depth and elevation distribution of the utility tunnel struc-ture,this paper proposes targeted treatment measures to ensure the safety and stability of the proposed utility tunnel structure.
