静压方桩的试桩施工技术
|
摘要
安徽省马鞍山经济技术开发区科技创新产业园工程项目的基底土质复杂、分布不均,并处于软硬土层交汇、过渡区域,地基存在不均匀沉降,导致现场压桩施工经常遇到土质差异的情况,使成桩困难。基于此,通过试桩,并结合现场实际地质情况,对设计桩长、设计压桩力进行合理配置,从而保证了压桩力,确保顺利成桩,避免了工程桩浪费,亦为后续施工奠定了基础。
The basal soil of the Science and Technology Innovation Industrial Park of Maanshan Economic and Technological Development Zone in Anhui Province is complex and unevenly distributed. It is located in the intersection of soft and hard soil layers and transition areas. The uneven settlement of foundation often leads to the difference of soil quality during the site piling construction, which makes pile formation difficult. Based on this, through the test pile and combined with the geological conditions, the design of the pile length and the piling force are properly arranged to ensure the smooth pile formation, to avoid the waste of engineering piles and also to lay a foundation for subsequent construction.
