Design and Construction of Prestressed Highstrength Concrete Pile on Oil Storage Tank Foundation/Cao Yunfeng1,Wang Aiguo2(1 China Textile Industrial Engineering Institute,Beijing 100037,China; 2 Beijing City Construct Group No1 Company,Beijing 100086,China)
Abstract:According to engineering geology,time limit for the project,mechanics and settlement property of oil storage tank foundation and so on,prestressed highstrength concrete piles are applied in these foundations.Three kinds of calculation methodes are considered due to characteristic value of single pile bearing capacity,that refers to design of pile collocation,and the main questions in construct foundations are summarized.By surveying the oil storage tank,the two settlement differences of oil storage tank can satisfy the codes.The design,construction and survey are introduced.It can be referred to similar e
ngineerings.
Keywords:prestressed highstrength concrete pile; oil storage tank foundation; construction;  settlement
