Soil Nailing In The Kunming Area Of ​​soft Soil Engineering Design And Construction Of Technical Analysis

Soil-nailing technology is a new stoopable soil of technology that in picking earth, and keep stabling the side of slope, it is a way of advanced support to strengthen earth project. The article is researching and studying information, it is comprehensive retrospect to development and circumstance with soil-nailing technology.The article is coalitioning with the geological characteristic and the project example in Kunming soft soil ground, it emphasize and study main contents that the soil-nailing's making, it is operating performance and the principle of work, it is breaking mode and deformation in the soft soil ground, need conditions used in design,main contents, capital system ,it used terminal equilibrium analysis system to figure theory, and construction schema , construction technical, construction system and control, and so on connected contents. It is analyzing and summarizing to arrive :(1) Soil-nailing used in Deep foundation Pit in Kunming is actable, safety, economical; (2) Structure design in soil-nailing must pressing design standard to figure, and it consider project comparison, experiential think and detailed reconnoiter proect geological. Construction design of Soil-nailing technology is used terminal equilibrium analysis system to analysis stabilization reckon, with controlling deformation, it care to influence little environment. (3) Soil-nailing technology use soft soil foundation in deep foundation pit, construction process must control speed, subsection construction, instantaneous retaining. Preventing influence with under water, it control quality of wall, it consider construction monitoring and control construction system. (4) Soil-nailing technology is moving design and information of construction. In this paper, the research offer available design theory basis and construction technology experiences with same projects in kunming area.
