Building Slope Supports And Protections Plan Shaping Research In Yan'an Area City Mountainous Region Development

Along with our country economic development swift developing and western big development implementation, the western many like Yan'an such mountainous region city is compelled land resource's limit to start to the hillside region development, under this background, the Yan'an area construction side slope supports and protections plan's shaping has received more experts and scholar's attention, also has more and more important strategic value and the practical significance to the loess side slope's research, chooses suits in the Yan'an area supports and protections plan and carries on to the plan optimal is this topic research main purpose. Chooses suits the Yan'an area construction side slope supports and protections the plan, both must satisfy the safe premise, and must the reduced investment as far as possible.This article through to the Yan'an area terrain landform, the climate hydrology, the gneiss project characteristic and the engineering geology classification and the pitch classification and the Yan'an area level of development of society carries on the analysis summary, falls wet to the Yan'an area the loess side slope characteristic and the Yan'an area terrain, geological, the building side slope carries on the analysis highly, union project case study influence stability of slope and side slope supports and protections plan primary factor; has studied the Yan'an area loess side slope main supports and protections plan, and analyzes the respective characteristic and in the Yan'an area compatibility, has obtained the supports and protections plan which first uses in the Yan'an area is the piling supports and protections, mainly uses supports and protections plan gravity type retaining wall, anti-slide pile, pile-prestressed anchor supporting structure and so on, the massive project example analysis which already to do through bright was willing the theory union obtained the anti-slide pile in this area "the reasonable application scope", beside may select its supports and protections pattern in "the reasonable application scope", And to determine the pile of "reasonable application" corresponding control parameters "corresponding single pile per unit length along the longitudinal slope soil (per meter) of the maximum bending moment".Thus obtains this local construction side slope shaping the reference standard and the general procedure, and unifies the project example to confirm.
