Application Research Of Cone Penetration Test In YellowRiver Deposit Plain Soil Of Zhengzhou

Cone Penetration Test(CPT) has speed quick,data continuous,emersion good, operation convenience etc. advantage. As an important in-situ soil testing method,CPT has been accepted by more and more geotechnical engineers. This paper first analyzes and introduces the development, present condition and theories foundation of CPT. Combine the practice in YellowRiver deposit plain Soil of Zhengzhou to explore of application carried on research.this paper discusses and studies the application of CPT. This paper research work and result as follows:1.Induce summary in YellowRiver deposit plain Soil of Zhengzhou of foundation soil quiet the dint touch to explore curve of characteristic, for make use of quiet the dint touch to explore data to carry on a soil layer divide the line and soil analysis etc. provided reference basis.2.For pair the bridge penetration cone of result with have already have list the bridge penetration of the experience result combine, summary concerning go into the specific penetration resistance with CPT to carry convert of tip resistance, shaft resistance relation in YellowRiver deposit plain Soil of Zhengzhou; Induce summary the quiet dint touch to explore with foundation soil of bearing capacity, compr modulus (Es) related formula, after pass this empirical formula calculation, get the strength parameter of with transform parameter to match more actual circumstance.3. Investigated to make use of CPT to touch to estimate to be applicable in YellowRiver deposit plain Soil of Zhengzhou to prepare to make ultimate bearing capacity of precast concrete pile have of dint engineering application value empirical formula. Summary make use of CPT to explore and silty sand,sandy soil liquefaction discretion of the empirical formula in YellowRiver deposit plain Soil of Zhengzhou, for silty sand,sandy soil liquefaction of discretion provide another kind of vialble method.
