Study On The Theory Of Settlement Control And The Design Method About Mixed Soil-cement Piles In Composite Foundation

With the increasing of national economy and the accelerating of cityward course, the project of construction makes a rapid progress,then companied with the increasing of inferior geological condition. We must deal with the crude soft soil artificially in order to meet the demand of groundsill intension, distortion and anti-seismic etc. Mixed Soil-cement Piles composite ground is widely used in varies project because of it's remarkable economical benefits and constructing conveneonce-shortcutly without no circumstance pollution.However, the history of Mixed Soil-cement Piles reinforcement technique is only about tens years from invented to now. Not only mechanism of reinforcement but also design, computing method have some faultiness .Some are still in the state of discussion researchSettlement computing in the design theory of Mixed Soil-cement Piles composite ground is not researched as maturely as bearing capacity computing because the means of technique and engineering-measure data are absent. So the methods of design and computing about limit condition of bearing capacity is still adopted in present criterion.Under the precondition of meeting the demand of construction's using function, the main content that is researched in this article is how to make the scheme of Mixed Soil-cement Piles composite ground on the safe side economical and reasonable, according to the rule of the design for deformation controlThe article, which is based on formers' theory and practice, combining with the example of engineering, utilizing the tool of MATLAB.5.0, using optimizing by plural modality method, makes a primary discussion on the design parameter of the scheme for Mixed Soil-cement Piles composite ground, according to the rule of the design for Settlement controlment method. Then we can get some useful conclusion which has definite instructive meaning for engineering practice.
