塑性混凝土防渗墙具有弹性模量低、极限应变大的优良特性,在地下防渗墙工程中应用较为广泛,技术日趋成熟,但拟作为管桩复合地基褥垫层材料国内尚无成熟经验可借鉴。本文作者通过大量的试验对裕溪节制闸除险加固工程管桩复合地基褥垫层配合比进行优化,最终满足该工程对塑性凝土强度、弹性模量、渗透系数等指标的要求,达到预期的效果。 Plastic concrete impervious wall has the characteristics of low modulus of elasticity and large ultimate strain. It is widely used in underground cutoff walls and the technology is maturing. However, there is no mature experience in the field of plastic concrete cutoff wall Learn from Through a large number of tests, the author optimizes the mix proportion of the Cushion of the Yuxi Barrier Gate Project and finally meets the requirements of the project such as the strength, modulus of elasticity and permeability coefficient of the plastic concrete so as to achieve the expected Effect.
