［摘要］柱下独立柱基+防水板形式或桩承台+防水板形式中存在某些因素会对防水板受力有影响。现通过对软垫层材料力学性能进行市场调查和实际分析，表明沉降量、浮力对防水板的受力起着决定性的作用。鉴于现行规范没有对防水板的设计作明确规定，通过设计实例来说明如何正确合理地进行基础+防水板的设计。

Abstract:Some factors existing in independent foundation under column and waterproof plate form or pile cap and waterproof plate have effects on waterproof plate mechanics. Through market research and practical analysis on the mechanical properties of soft cushion layer materials, it shows that the settlement and buoyant force play a decisive role in mechanics of waterproof plate. In view of that the existing norms do not have clear regulations for the waterproof plate, how to correctly and reasonably carry out the design of the foundation and waterproof plate was illustrated through the practical design examples.

Keywords:waterproof plate; soft cushion layer; buoyant force
