若干重大隧道与轨道交通工程的防水创新技术

Some new waterproofing techniques used in major tunnels and mass transit projects

介绍了近年华东地区建设的若干重大隧道与轨道交通工程在防水设计与施工技术中采用的若干创新技术,比如混凝土施工用模板及其支撑体系,混凝土养护的保温材料,混凝土“双掺”技术,地铁区间隧道联络通道复合防水层,隧道运营“健康”与安全监测以及耐久性指标K(混凝土渗透系数)、Dclˉ(氯离子扩散系数)的检测等。

The article introduces some new techniques in waterproofing design and application developed for major tunnel and mass transit projects in recent years in East China,such as form and bracing system for concreting,insulation material for concrete curing,concrete“double addition”technique,composite waterproofing in connecting channel of station -to -station tunnels,“health”and safety monitoring for tunnel running,test of durability index K(Concrete permeability coefficient )and D cl- (determination of chlorion diffusion coefficient ),etc.
