Application And Research Of Deep Mixing Pile On Foundation Seepage

Nowadays there are many kinds of soft soil foundation reinforcement measures。 Deepmixing pile as a new type of foundation treatment technology for its fast construction speed,less construction investment, good strengthening effect and is widely used in many kinds of softsoil foundation reinforcement engineering.At the beginning of deep mixing pile, it is used for compound foundation reinforcementand improves the foundation bearing capacity to decrease the settlement of soft ground. Withthe development of construction machinery and construction technology, deep mixing pile as arelatively new seepage control measures are widely used in water conservancy engineering,deep mixing pile is used as Cut-off wall has many advantages, such as simple in constructionmachinery, construction fast, low cost, no environmental pollution and obvious seepage controleffect， etc.The article introduces different kinds of foundation and ground treatment methods,analysis and summarizes the deep mixing pile in the reinforcement mechanism of materials andconstruction equipment, construction technology and technical key points of quality control,etc. It also summarizes the design calculation and subsidence research of deep mixing pilecomposite foundation. It also puts forward the principle of choosing different constructionmachinery and construction technology, and solving methods and control measures which wereliable to occur during the construction process of deep mixing pile.The chapter four begins with the background of the engineering example, combining withrelated seepage theories, using relevant seepage program, ANSYS, GEO Studio software forthe dam foundation seepage simulation analysis, and analyzes the seepage results, andconcludes that the deep mixing pile is feasible in the dam foundation seepage control, thus forthe deep mixing pile anti-seepage technology in-depth study and promote the use of providecertain technical reserves.
