青海省公路桥梁概念设计中的几个突出问题
Several outstanding issues in the conceptual design of highway bridges in Qinghai province
【摘要】 通过审查青海省近百座公路桥梁设计图纸,发现在"导流堤设计、冲刷计算、桥梁设计宽度、桥梁抗震"的方面存在严重的概念问题,影响桥梁安全。文中针对这4个突出问题分别进行了论述,并提出了相应的设计措施。
【Abstract】 Conceptual design is a specific design guide,throughout the design process.Through a review of hundreds of highway bridge design drawings,found that some serious conceptual problems of the design,these issues directly affect bridge safety.In this paper,four issues are discussed,Proposed measures to guide the design.
