6、地下工程防水性能不好致使地下水渗漏到工程内部将会带来一系列问题:如影响人员在工程内正常的工作和生活使工程内部装修和设备加快锈蚀使用机械排除工程内部渗漏水需要耗费大量能源和经费而且大量的排水还可能引起地面和地面建筑物不均匀沉降和破坏另外据有关资料记载美国有20%左右的地下室存在氡污染而氡是通过地下水渗漏渗入地下工程内部聚积在地下工程内表面我国地下工程内部氡污染的情况如何尚未见到相关报道但如地下工程存在渗漏水则会使氡污染的可能性增加地为适应我国地下工程建设的需要使新建续建改建的地下工程能合理正常下工地使用充分发挥其经济效益社会效益战

7、备效益因此对地下工程的防水设计程防水技术规范施工内容作出相应规定是极为必要的在设计和施工中要贯彻质量第一的思想把确保质量放在首位1.0.2(原规范1.0.2修改条文)根据1998年3月建设部标准定额司召开的规范修订协调会的精神本规范不再涉及验收规范的内容故删去原条文中验收的内容目前城市市政隧道修建越来越多为适应这一情况在本条中增加市政隧道这一内容资料编号关于水底隧道根据施工方法可分为矿山法盾构法沉管法等由于目前国内沉管法施工的水底隧道数量太少所以这次修编时未将沉管法的有关内容纳入1.0.3(原规范1.0.3修改条文)防水原则既要

8、考虑如何适应地下工程种类的多样性问题也要考虑如何适应地GB50108--2001下工程所处地域的复杂性的问题同时还要使每个工程的防水设计者在符合总的原则的基础上可根据各自工程的特点有适当选择的自由原规范提出的防水原则基本符合上述要求从修编过程中征求的意见来看使用
