摘　　要：根据GB 55030—2022《建筑与市政工程防水通用规范》规定,一级防水的防水做法要求不少于3道,其中外设防水层要求不少于2道,采用复合防水层是防水设计、施工的常规做法。通过对目前建筑及市政工程中应用最广的不同防水卷材与防水涂料进行复合,以正拉粘结强度及其破坏形式为依据,分析复合防水层之间的相容性,为复合防水层设计、施工提供选材依据。结果表明,非固化橡胶沥青防水涂料与改性沥青防水卷材和PVC防水卷材都具有较好的复合效果。According to the national standard GB 55030-2022"General code for waterproofing of building and municipal engineering",the waterproofing practice for first-class waterproofing requires a minimum of 3 layers,with at least 2 layers dedicated to external waterproofing.The conventional approach in waterproof design and construction involves utilizing composite waterproof layers to achieve the desired level of water resistance.This paper combines various commonly used waterproof materials in architectural and municipal engineering applications,analyzing the compatibility between these composite waterproof layers based on bond strength and damage patterns.This analysis provides a basis for material selection during the design and construction of composite waterproof layers.The results show that the non-curing rubber asphalt waterproof coating has good composite effect with modified asphalt waterproof coating and PVC waterproof coating.
