楔形管桩沉桩及桩端后注浆可视化模型试验
Visualization model test on tapered pipe pile installation and pile tip grouting process
摘要
Abstract
Based on both transparent soil and PIV technique, one visualization model test on precast tapered pile installation and pile end grouting construction process was carried out. The soil displacement around the tapered pile during pile installation was measured and the shape of the formed enlarged pile base was also observed during pile end grouting process. The test results showed that the soil displacement around the tapered pile was different from that of the uniform section pile. The maximum displacement was located on the top around the pile and the pile end grouting exhibited the typical cavity expansion mode. Transparent soil and PIV technique could visualize the installation and pile end grouting process of tapered pile, provide more information for pile design and construction and would have a wider application in pile-soil interaction problems.关键词
