摘要 岭西八路综合管廊工程为吉林省公主岭市为适应城市快速发展需求、提升市政建设设计标准而新建的七条管廊之一,调研分析了该管廊的地理位置、场地地质条件及水文地质情况。设计入廊管线包括热力管道、给水管道、再生水管道、电力电缆和通信线缆。根据技术标准,对该综合管廊的平面、纵断面、横断面等总体进行设计;针对管廊处于古河道区域所遇具体问题,详述了基坑支护、管廊配筋、地基、抗浮、防水等结构设计要点。 The Lingxi 8th Road Utility Tunnel Project is one of seven newly built utility tunnels for adapting the rapid development demand of city and upgrading the municipal construction standards in Gongzhuling City of Jilin Province.The geographic position,site conditions and hydrogeological situation of this utility tunnel are studied and analyzed.The pipelines into utility tunnel are heating pipeline,water supply pipeline,reuse water pipeline,electric power cable and communication cable.According to the technical standards,the plane,vertical section and cross section of this utility tunnel are designed.In view of the specific problems encountered by the utility tunnel in the ancient river area,the key points of structural design of foundation pit support,utility tunnel reinforcement,foundation,floating resistance and water resistance are described in detail.
