岩体裂隙发育区域的地下排水设计施工措施探讨

Design and Construction of Underground Drainage in Fractured Rock Region

在岩体中裂隙较多且地下水发育的区域修造建筑或道路时,渗水是影响施工的主要因素,特别在雨季降雨量较大时,没有完善的地下排水设施,将直接影响建筑及路面的使用性能,减少其使用寿命,严重影响运营安全。以无锡地铁某停车场为研究对象,从勘察、设计、施工等方面,系统研究了场内渗流区域排水设施的解决方案,分别提出库体结构基础和路基不同的预防技术措施,并对施工过程的质量控制关键点进行了强调,对于多裂隙山体附近大规模建筑的地下排水系统设计具有推广和应用价值。

During the work of buildings or roads in fractured rock or adequate groundwater region ,water seepage is the main factor affecting the construction, especially in the rainy season. The lack of underground drainage facilities will directly af- fect the construction and road usage performance, reduce its service life and seriously affect operational safety. Taking an under- ground metro park in Wuxi as a research object, this paper systematic studies the drainage solutions of the seepage area from the survey,design, construction and other aspects. It proposes different technical measures of structure foundation and embank- ment,emphasizes key points of construction quality control,which has application value in underground drainage system design for big construction in fractured rock region.
