透水混凝土桩的桩体材料试验研究

Research on the materials of pervious concrete column

根据复合地基排水性能对桩体材料的要求,采用正交试验法对影响透水混凝土的抗压强度和渗透系数的诸多因素,如水灰比、骨灰比及骨料级配等因素进行了研究,基于大量室内试验,提出了透水性混凝土的施工配合比。结果表明,该配合比下的透水混凝土既能满足复合地基桩体材料强度要求,同时具有理想的透水性能。

Considering the requirement of composite foundation on the column materials,orthogonality test is used to study the effects of some factors such as gradation of aggregate,mass ratio of aggregate to cement,mass ratio of water to cement on the properties of pervious concrete including permeation coefficient and compressive strength. Finally,the experimental mixture ratio is suggested to produce pervious concrete with desirable permeability,as well as the compressive strength that meet the request of column materials in composite foundation.
