摘要

古建筑夯土基座的长期渗漏对其上部结构安全性态和基座外观影响较大，探索基座顶部抗渗措施意义重大。为此，建立了与基座原型尺寸相比为1:18的缩尺模型，开展降雨入渗试验，研究基座顶部素土压实法和不同改性土换填法对基座的抗渗效果。结果表明：（1）当采用素土压实法时，适当增加基座夯土的干密度可降低降雨入渗影响，夯土整体干密度提高10%，降雨入渗影响深度可降低40%以上，增湿程度可降低50%左右，但整体挤密施工会对上部结构及基座外侧砌体结构产生过量侧向变形甚至开裂；（2）当采用5种改性土对局部进行换填时，三合土抗渗效果较好，糯米粉+稻草改性土次之，最终建议采取局部换填改性土和其他构造措施来改善古建筑夯土基座的抗渗性。

Abstract

The long-term seepage of the rammed earth foundation (REF) has a great influence on the safety of the superstructure and the appearance of the ancient building. It is vital to explore the anti-seepage measures for the top of the REF. In this study

a scale model with a size of 1:18 compared with the real size of the REF was established. The rainfall infiltration tests were carried out to study the anti-seepage effect of the plain soil with compaction method and different modified soils with replacement method on the top of the REF. The results showed that: 1) The rainfall infiltration was reduced by increasing the dry density of rammed earth by using compaction method. When the dry density of REF was increased by 10%

the depth of rainfall infiltration was reduced by more than 40%

and the wetting degree was reduced by about 50%. However

using compaction method could induce damage to the superstructure and the external masonry structure of foundation. 2) When the five kinds of modified soil were used for local replacement

the anti-permeability effect of tabia was better

followed by the modified soil of sticky rice flour and straw. Finally

it is suggested to adopt local replacement of modified soil and other structural measures to improve the anti-seepage effect of REF of ancient buildings.
