| With the rapid development of the economy, the development of top and high-rise buildings have become the trend of the future all around the world. Wherein Prestressed Pipe due to its convenient transportation, assembly is simple, pan with high strength, good bending performance, conditions for the development of higher pile capacity rapidly. On the basis of the construction process, pile testing is to evaluate the integrity of pile foundation, an important part of quality,also many productions have been acquired.Its restoration is very difficult, so in the construction process to detect defects in the pile, safety and reliability in the design process to determine the type of pile of pile testing so requests, to ensure that the foundation of security and stability.Based on the above, this paper summarizes the various pile testing methods at home and abroad, high-strength and PHC pile, for example, by comparing the field test and finite element simulation method of combining study the pile under static load test of the actual situation give some valuable conclusions.This paper mainly discusses the following aspects:(1)Necessity of pile foundation detection is discussed On the basis of comprehensive understanding of the development of pile foundation.(2)Discussion and analysis of the main method of pile foundation detection.(3)The basic of finite element method for pile foundation simulation is analyzed.And discussed the related functions and functions of ABAQUS software.(4)In comparison with the actual situationthe finite element simulation of the pile foundation is carried out by using the finite element software.Papers take single pile static load test, combined with ABAQUS finite element software to simulate on-site analysis. It found that the finite element method can be more accurately calculated the value of pile settlement under static load, and thus obtain Q ~ S curve, which provides an effective basis for the preliminary design of the pre-pile. |
