Study On Application And Practice Of Static Compression Pile In Nanning

With the rapid development of building industry and continuous advancement of construction technique, the use of pile foundation is more and more widely. Because of the difference in engineering geological conditions,economic condition,the requirement of the building and experience of Survey designer,project planner adopt distinct foundation type in different region。The study on construction technique for Static compression pile is the hot question on the use of foundation in these years。Many scholars at home and aboard carry out helpful exploration on the jacked-in pile form the aspects of theoretical analysis and construction technique。Although The construction of Static compression pile was affected by many factors,and has many uncertainties。All these made this problem regional and complicated。But with the vigorous advocate of geotechnical engineering,Static compression pile was universally accepted by engineers and technicians by means of it's advantages such as free from contamination,noiseless,dependable quality and reasonable cost,etc。And become one of the major Pile Styles of the multi-storey and tall buildings in Nanning. So come to understand the practical situation of Nanning, inquiry and summarize the practical experience suitable for Nanning,will provide useful reference on the use of this foundation types。This paper carried out the research and analysis as follows。①Present the service conditions of Static compression pile in both here and abroad especially in Nanning;②Analyzed,compared and summed up the research Status,construction methods and characteristics of static pressed pre-cast pile;③Carried out comparative analysis on Nanning's engineering geology and Pile Styles。And come to the conclusion that Static pressed pre-cast pile is suitable for Nanning Province。④Aimed at the features that the pile foundation has many influence factors and is underground, this paper researched into some crucial problems concerning static pressed pre-cast pile, and put forward the corresponding regional empirical parameters.⑤Through the practical analysis, this paper raised some matters need attention during construction of Static compression pile.Based on the study of Nanning's engineering geological features and Static compression pile's application, this paper put forward some valuable consulting viewpoints and improvements for the purpose of the safe and reasonable construction of Static compression pile.
