Analysis On The Settlment Of Soft Soil Foundation Treated With Gravel Pile

Because of the large amount of the settlement in soft ground, the foundation bearingcapacity, consolidation really long time and other engineering properties, it is difficult to meetthe requirements of the building of the highway, so we must take the appropriate measures forthe reinforcement to improve the condition of the foundation to improve the foundationbearing force, to ensure the quality of the project. Soft ground approach now very mature, inthe form of a variety, such as for the issuance of the dynamic compaction method, compositefoundation, drainage consolidation method, chemical reinforcement, at the same time eachSoft Foundation Treatment Methods own processing characteristics and scope of application.The role and not gravel pile composite foundation as a composite foundation, often used inthe treatment of soft foundation, its main replacement soft soil materials such as sand, gravel,or through the vibration of the pile, compaction The reinforcement part of the formation ofcomposite foundation with the purpose to improve the foundation strength. Gravel pile cannot only improve the bearing capacity of composite foundation, but also can reduce thesettlement after construction more convenient, less spending money, reinforcement relativelyshort time.This paper mainly relying Zunyi to of Chishui the highway soft foundation treatmentworks the rubble pile composite foundation, classification, role and mechanism gravel pilecomposite foundation. Then early relying project data collection and test conclusive evidence,the introduction of the gravel pile composite foundation design and construction methods.Soft Ground Reinforced soft ground, gravel pile body, gravel pile composite foundation andgravel piles numerical simulation analysis using finite element software, analysis of themechanism of action of the gravel pile composite foundation and force process, verify thefeasibility of the design. While waiting for the gravel pile composite foundation constructionsite single pile static load test test for detection of the pile, the strength characteristics treatedits soft subgrade bearing capacity to meet the design requirements, and then calculated basedon test results after. The gravel pile testing is completed subgrade fill and subgradedeformation observations by subgrade deformation observation can be seen Gravel PileComposite Foundation can not only greatly improve the subgrade bearing capacity of its workers after the settlement deformation and displacement deformation meet coderequirements. Summed up by this test section detects the ultimate bearing capacity of thegravel pilestatic load test method; through the gravel pile ultimate bearing capacity of singlepile static load test detection and data analysis to prove that a static load test gravel pileultimate bearing capacity, able to detect and verify a gravel pile composite foundationreinforced soft foundation treatment method is feasible, the test results to improve the gravelpile composite foundation reinforcement of the soft ground testing standards, as The mountainhighway soft subgrade design, construction provide a reference guide.
