摘要
研究目的:研究如何判定武广客专路基端承灌注桩桩端轻微离析或严重离析混凝土的厚度和性质。研究结果:反射波法检测桩身质量完整性可以判定桩端轻微离析或严重离析混凝土的厚度和性质;桩端轻微离析或严重离析混凝土通过单桩静载试验得知其承载力大于2000 kN。
Research purposes： The research is done on how to decide the thickness and characteristics of the slight segregated or serious segregated concrete on the end of column pile for the subgrade of Wuchang - Guangzhou Passenger Dedicated Railway.
Research results：The thickness and characteristics of the slight segregated or serious segregated concretes can be decided with the mass integrity of pile body made by reflection seismology. It can be seen from static test for single pile that the bearing capacity of the slight segregated or serious segregated concrete on the end of column pile is more than 2 000 kN.
