摘　　要：简支斜梁桥与简支正交桥在结构受力上存在一定的差异,斜交角度不超过一定的范围时,这种差异比较小。该文以某斜交角为70°的实桥的承载力鉴定检测为例,对斜梁桥采用不同的理论计算方法,并对其计算结果进行比较。通过桥梁各种项目的检测,对该桥的承载能力进行评估,为桥梁管理部门提供科学的决策依据。The simple-supported skew bridge is a certain different from the simple-supported right bridge on the bearing of structure. When the skew angle does not exceed a certain range, this difference is smaller. Taking the bearing capacity appraisal of a bridge with 700 skew angle as an example, the article uses the different theoretical calculation methods for the skew bridge, and compares their calculating results. Through various inspecting items of bridge, the bearing capacity of this bridge is evaluated to provide the scientific policy-making basis for the bridge management departments.
