Study On Slope Project Design In New Campus Of Fuzhou Armed Police Academy

Slope is a common form of engineering construction project. For the same slope, there are a variety of supporting governance programmes. How to adjust measures to local conditions, scientifically and rationally take the most suitable for the actual characteristics of slope supporting treatment scheme is important to the design unit. Based on new campus of Fuzhou Armed Police Academy complex slope, briefly introduces the basic situation of the project and the common slope supporting type working mechanism. Fully combining the actual conditions of construction site, according to analysis different sections of the slope support scheme, finally obtains the optimized scheme, and numerical simulation is carried out by using the finite element software. Then, demonstrated the preferred scheme is technology advanced and economic rationality, the research results provide guidance for the slope engineering design. According to the geological environment conditions, the main research contents in different sections are as follows:1) K0(K0+0～K0+120) section is excavation slope, slope height larger, rock is integrity, according to geological conditions features selected different supporting scheme, intends used slope ratio method, framework+prestressed anchor cable (rod) support nursing, anchor rod lattice and short nail active protective network, by the technical and economic comparison to determine the optimization programme, and numerical simulation is carried out by the finite element software Slide to verify the feasibility of the optimization scheme.2) K1-1(K1+0～K1+200) section is fill slope, soft soil deep, the foundation bearing capacity is poor, plans to use the supporting scheme is gravity retaining wall+bored pile combined with cement mixing pile foundation treatment, counterfort retaining wall+CFG pile and cement mixing pile foundation treatment, reinforced earth retaining wall+CFG pile combined with cement mixing pile foundation treatment, through technical and economic comparison to determine the optimal scheme, and numerical simulation is carried out by the finite element software Plaxis to verify the feasibility of the optimization scheme. 3) K1-2(K1+200-K1+380) section is fill slope, which K1+200-K1+340section of silt soil was thick, about10m, taking into account the ease of construction, plans to use the supporting scheme is reinforced earth retaining wall+CFG pile foundation treatment; K1+340-K1+380section the foundation is better, considering the construction convenience and cost, plans to use the supporting scheme is reinforced earth retaining wall supporting scheme for slope treatment.4) Combined with the complex slope supporting design in the new campus of Fuzhou Armed Police Academy, using Plaxis to design and calculate the reinforced earth retaining wall in soft soil, and analyzed the results, and pointed out that the rationality of the slope treatment schemes.
