Study on Vertical Bearing Capacity and Time Effect of the Jacked-in PHC Pipe Pile in the Cohesive Soil Area Hongliang Zuo1, a, Lei Wang2, b, Hongying Gao3, c and Liang Guo1, d 1College of Civil Engineering, Northeast Forestry University, Harbin, Heilongjiang, 150040, China 2Heilongjiang Province Construction Technique Development Centre, Harbin, Heilongjiang, 150046, China 3Tianjin Land Resources and House Vocational College, Tianjin, 300270, China azhl9163@163.com, bwanglei_lls@yahoo.com, clinker8224@163.com, dgld1128@163.com Keywords: cohesive soil area, jacked-in PHC pipe pile, vertical bearing capacity, final pressure, time effect.
According to the time effect formula, the vertical bearing capacity at different periods of the jacked-in PHC pipe pile can be obtained, the cost of the foundation engineering can be reduced by considering the time effect influence to the vertical bearing capacity of the jacked-in PHC pipe pile.
The higher ultimate end resistance and vertical ultimate bearing capacity of single pile can be obtained, and then the cost of the foundation pile engineering can be reduced sharply.
Besides, the vertical bearing capacity of the jacked-in PHC pipe pile will change along with the interruption period lengthens, this is called the time effect of bearing capacity which is important for reduce the cost of the engineering that considering the time effect influence to vertical bearing capacity of the pile adequately.
