摘要
双排桩-锚杆结构在深基坑支护中有着广泛应用,然而由于其受力机理较为复杂,目前对这种支护结构的理论研究还远远落后于工程实践.基于某基坑工程实例,采用有限元软件Ansys,研究了基坑土体的沉降和双排桩-锚杆结构的受力以及变形规律,并基于计算结果对支护结构进行了配筋设计.结果显示,基于有限元法的双排桩配筋法能考虑土体本构关系,其配筋量比传统的工程配筋量减少10%~23%,因而具有明显的优越性.
Double row pile-anchor structure is widely used in the deep foundation pit supporting engineering.At present,the theoretical research on this kind of support structure is far behind the engineering practice due to its complicated mechanical mechanism.Based on an example of a foundation pit project,the settlement of foundation pit soil,the stress and deformation law of double row pile-anchor structure were studied by using the finite element software Ansys.According to the calculation results,the reinforcement design of the support structure was carried out,The result shows that the reinforcement method of double-row pile based on finite element considers the constitutive relation of soil,and the reinforcement quantity is reduced by 10%-23%compared with the traditional engineering reinforcement quantity,which provides the reference for the reinforcement design of similar structures.
