摘要:
为研究斜交异形箱涵整体结构的受力性能及变形规律,针对西安站改工程地下大跨三孔斜交异形箱涵通道,利用有限元分析软件ABAQUS建立了箱涵结构的三维精细化有限元模型,重点研究了箱涵整体结构在正常状态下的受力特性和极限状态下的最终破坏模式; 通过分析箱涵各构件的应力分布、裂缝开展以及最大变形,对整体模型进行了可靠性分析,并提出了箱涵相关设计建议。结果表明:箱涵整体结构的变形主要来自顶板和底板的弯曲变形以及侧板的剪切变形,裂缝主要集中于顶板底侧和板墙隅角处; 正常使用状态下箱涵各构件最大变形以及钢筋和混凝土最大应力均远小于规范限值,符合设计要求; 箱涵在开洞部位、板墙隅角和斜交段钝角处易出现应力集中现象,应在相应位置加强构造措施; 当变形缝处斜裂缝沿箱涵纵向长度与箱涵跨度的比值K≥0.77时,建议采用斜交计算理论,当K<0.77时,建议采用正交计算理论,但应在斜交变形缝处增设补强钢筋进行加强,K值对三孔、板墙开洞、斜交等类似工程具有一定的参考价值。
Abstract:
In order to study the mechanical property and deformation law of the integral structure of oblique special-shaped box culvert, aiming at the underground long-span oblique special-shaped box culvert channel of Xi'an Railway Station Reconstruction Project, a three-dimensional refined finite element model of the box culvert structure was established by using the finite element analysis software ABAQUS, focusing on the mechanical property of the integral structure of the box culvert in normal state and the final failure mode in ultimate state. The stress distribution, crack development and maximum deformation of each component of the box culvert were analyzed. The reliability of the whole model was analyzed, and the relevant design suggestions of the box culvert were proposed. The results show that the deformation of the integral structure of box culvert mainly comes from the bending deformation of the roof and bottom plate and the shear deformation of the side plate. The cracks are mainly concentrated at the bottom of the roof and the corner of the slab wall. The maximum deformation of each member of box culvert and the maximum stress of reinforcement and concrete under normal state are far less than the limit value of code, which meet the design requirements. The stress concentration of box culvert is easy to occur at the opening position, the corner of slab wall and the obtuse angle of skew section, so the structural measures should be strengthened at the corresponding position. When the ratio of the longitudinal length of the inclined crack along the box culvert to the span of the box culvert at the deformation joint K≥0.77, the oblique intersection theory is recommended, and when K<0.77, the orthogonal calculation theory is recommended, but the reinforcing steel bars should be added at the oblique deformation joint to strengthen. K has certain reference value for similar projects such as three holes, slab wall opening, skew intersection.
