Effect Analysis On Dynamic Compaction Soiltreatment In The Aviation Assembling Workshop

With the continuous development of infrastructure, general dynamic compactionmethod has exposed its limitations in dealing with loose fill,thick mucky soil area and theexcavated area. In response to these developments, new columns hammered compaction isgood at super deep compaction, compaction replacement, and so on.The Page studied on the test and detection of dynamic compaction in the aircraftfactory. First of all, we’ll develop information of site location and reinforcing requirements,we will design dynamic compaction, design dynamic compaction including choosingdynamic compaction test area, selecting compaction parameter and arranging the testprocess.Then through field testing, including sunk of dynamic compaction, standardpenetration test, dynamic penetration test, static loading test and soil test, we will analyzethe effect of dynamic compaction, get the reinforcment effect,such as sinks, compressionmodulus and bearing capacity of composite foundation, adjust design parameters ofdynamic compaction, and propose modified treatment measures. Furthermore, qualitativeanalyzed the influence factors of bearing capacity of composite foundation and briefed thecurrent calculation method what problems it is has at home and abroad. Based on thetheory of cavity expansion and used "group pile analysis method"to get the compositefoundation bearing capacity of plum pile under the condition of flood and independentfoundation under column calculation. Finally,The page use FLAC3D to discuss dynamiccompaction parameters on effect of bearing capacity of composite foundation byqualitative or quantitative analysis. Combined with field test, it is used "group pile analysismethod" to simulate the action of pier and soil, analyze the mechanism of compositefoundation and dicuss the influence factors which including pile length, pier diameter, piercompression modulus, pier density, cushion thickness,pier spacing and the shape of thepile...
