针对山区渡槽容易受其自身结构以及水、风荷载的影响,文章以黔中水利枢纽一期工程为例,分析了徐家湾等4座连续刚构渡槽背景,浅析山区渡槽大直径桩基设计、桩基施工、检测方法和基桩质量检验的特点。结果表明,要想保证山区连续刚构渡槽桩基的应用效果,必须根据工程所处的地质情况明确科学合理的桩基设计内容。
In view of the mountain aqueduct susceptible to its own structure and the impact of water and wind loads, this paper analyzes the background of four continuous rigid-framed aqueducts in Xujiawan, Design, construction of pile foundation, testing methods and foundation pile quality inspection. The results show that in order to ensure the application effect of continuous rigid-frame aqueduct pile in mountainous area, it is necessary to define the scientific and rational design contents of pile foundation according to the geological conditions in the project.
