透水混凝土桩具有较高的渗透性和强度。振动沉管施工安装过程中，液化后的土体迁移到PCP中，造成堵塞。为了研究PCP堵塞，进行了模型试验和X射线计算机层析分析。对堵塞深度、孔隙度和超孔压消散进行了表征。评价了土工布对PCP防堵塞的效果。结果表明，随着靶区孔隙度和取样深度的增加，PCP堵塞深度显著增加。提出了评价五氯酚堵塞的初步模型。结果表明，用土工布包裹PCP可以解决堵塞问题。
Pervious concrete piles (PCP) have high permeability and strength. During installation by vibrating-sinking tube construction, liquified soil migrates into PCP, leading to clogging. To study PCP clogging, model tests and X-ray computed tomography analyses were carried out. The clogging depth, porosity, and excess pore water pressure dissipation were characterized. The effect of geotextile on PCP anti-clogging was evaluated. The results show an increase in target porosity and sampling depth significantly increased the PCP clogging depth. A preliminary model was proposed to evaluate the clogging of PCP. The results show that clogging can be solved by surrounding PCP with geotextile.
