PHC管桩在复杂地质条件下的工程实践

Project Practice of PHC Pipe Pile under Complex Geological Conditions

介绍预应力高强混凝土 (PHC)管桩在某工程复杂地质条件下采用工字型钢 PHC管组合桩、小钢管引孔和信息化施工等技术措施 ,成功地解决了嵌岩深度、块石挤桩和截桩量大等问题 ,取得了较好的效果。

In this article, the author introduces some technical methods adopted in a project in which Pre stressed High strength Concrete (PHC) pipe piles were used under complex geological conditions. These methods included combination piles with I shaped steel and PHC pipe, small steel pipe guiding, information construction and so on, successfully solved such problems as embedding depth, rock pressing, broken piles and so forth and got better effects.
