Study On Reflection Wave Method On Testing The Bored Pile And Supervision And Control Of Construction

The bored pile is applied widely. But there are lots of problems to study with testing the quality of pile body. Such as testing short pile, effective length of pile, correct identification of waveform.This paper takes the reflected wave method testing the bored pile as starting point, makes a further discussion of the problems of short pile,effective length of pile,abnormal wave in Shenyang local areas; puts forward the favorable slenderness ratio and maximum length of pile in this areas which was tested by reflected wave. This paper discusses on the supervision and control measures of quality of construction and the Accidents treatment of constructing to ensure the quality of pile too. There are mainly some aspects:Analysis the reflected wave theory and the difference of practical engineering between it. Discuss the main points of testing pile in practical engineering.Analysis the applicability and localization of reflected wave testing pile in some areas such as Qinpanshan Shenyang on the background of some construction project in those areas.And put forward the accidents treatment of construction and the supervision and control measures of quality of construction according to the case of construction practical engineering.At last, the conclusion:when the slenderness is 4～5 and pile length is less than 57m, the bored pile can be tested by reflected wave in shenyang areas and so on.
