西藏光伏项目可行性研究阶段光伏阵区桩基础形式比选研究

Comparison and Selection of the Pile Foundation Structure for the Array Area of Xizang Photovoltaic Project in Feasibility Study Stage

在光伏项目可行性研究阶段,科学确定光伏阵区的桩基础形式,是保证项目建设安全、质量,并提高工程建设经济性的重要环节。根据项目建设特点,本文通过半定量和定量两个阶段,对光伏阵区各类可选桩基础形式进行了全面对比和分析,推荐采用螺旋钢管桩基础,全面替代目前西藏光伏项目的阵区基础全部使用的钢筋混凝土灌注桩,既可保证桩基工程质量,又能节约投资与缩短工期。

In the feasibility study stage of photovoltaic projects,selection of the pile foundation structure for the array area is an important procedure to ensure the construction safety and quality and improve the construction economy.Considering the specific characteristics of the project,various optional pile foundation forms of the array area are analyzed and compared comprehensively with semi-quantitative and quantitative methods.The spiral steel pipe pile foundation is recommended to completely replace the reinforced concrete cast-in-place piles used in array areas of current photovoltaic projects in Xizang,which can not only ensure the quality of the pile foundation work,but also save investment and shorten the construction time.
