预应力方桩水上沉桩定位控制及计算解析

Positioning Control and Calculation Analysis of Waterborne Sinking of Prestressed Square Piles

以西洋一级渔港项目北澳80 HP码头工程施工为例,简要分析了预应力方桩水上沉桩的定位控制方法,通过解析计算过程形成一套简易快速的条件判定公式,减少测量人员现场工作及计算时间,降低计算出错率,保障施工的流畅性,并有效提高现场沉桩的精准定位及施工速度。

Based on the construction of BeiAo 80 HP berth of Xiyang class-I fishing port,the positioning control method for the waterborne sinking of prestressed square piles is briefly analyzed,and a set of simple and fast condition determination formulas are produced in the process of calculation analysis.The application of the research results reduces the field working and calculation time spent by the surveyors,lowers the calculation error rate,ensures normal construction,precisely determines the field pile sinking position and speeds up the construction.
