When pervious concrete is used as pile material, both high strength and water permeability will be available. By comparing the strength and permeability of pervious concrete with different aggregate size (3–5 mm and 4–6 mm) and porosity (20%, 25%, 30% and 35%), the recommended aggregate size (3–5 mm) and porosity (30%) can be achieved. To investigate the installation effect and bearing characteristics of the pervious concrete pile composite foundation, the excess pore water pressure, settlement, pile-soil stress ratio and skin friction were recorded in the model test. Results show that, compared with the impervious pile, the pervious pile can significantly accelerate the dissipation of excess pore water pressure after pile installation, and in the loading test can shorten the consolidation time by 30.3%, increase the skin friction 0.12 kPa averagely, reduce the peak value of excess pore water pressure by 30.2%, and increase the characteristic value of bearing capacity by 43.2%. When the linear penalty method is applied, and the friction coefficient is 0.6, compared with the test, the deviation of simulated skin friction is the largest, being about 15%, so in general the model test results are reliable.

当使用透水混凝土作为桩材时，既具有高强度又具有透水性。通过比较不同骨料尺寸（3-5mm和4-6mm）和孔隙率（20%、25%、30%和35%）的透水混凝土的强度和渗透性，推荐骨料尺寸（3-5mm）和孔隙率 (30%) 可以实现。为研究透水混凝土桩复合地基的安装效果和承载特性，在模型试验中记录了超孔隙水压力、沉降、桩土应力比和表面摩擦力。结果表明，与抗渗桩相比，透水桩能显着加快桩后超孔隙水压力的消散，在加载试验中可将固结时间缩短30.3%，表面摩擦系数增加0. 平均12 kPa，超孔隙水压力峰值降低30.2%，承载力特征值提高43.2%。当采用线性惩罚法，摩擦系数为0.6时，与试验相比，模拟蒙皮摩擦偏差最大，约为15%，因此模型试验结果总体上是可靠的。
