Analysis of Pile Foundation Construction in Xizang Photovoltaic Project Site
Xizang has sufficient solar resources,which is very suitable for the development of photovoltaic generations.Pile foundation construction is the basic procedure in photovoltaic site construction,which has a significant impact on the progress and subsequent installation quality of support components in the photovoltaic site.Therefore it is necessary to study and analyze the construction of pile foundations.This paper analyzes the pile foundations of six photovoltaic projects in Xizang.There are two main types of pile foundation,one is concrete pile and the other is spiral pile.The construction of concrete pile foundation has significant time limitations,with relatively long construction time and high construction cost,but it can adapt to various geological conditions.Spiral pile foundation has no time limitations,short construction time,and relatively low construction cost,but it has certain requirements for geological conditions.When the geological condi-tions meet the requirements,it is recommended to prioritize the use of spiral pile foundation construction.
