prestressed concrete beam bridge

基本解释

During construction of a large span prestressed concrete beam bridge, a set of stress transduers are installed at its key sections for measuring the structure strain.
将钢弦应变传感元件用于大跨度预应力混凝土梁桥施工中，对箱梁关键截面的应力实施跟踪测试和控制。
The main difficulty in analysis of unbonded prestressed concrete beam bridge is the coupling between the sectional strength of member and the whole structural deformation of member.
分析无粘结预应力混凝土梁桥的主要困难，在于构件的截面强度和构件整体变形耦合。
The long-span prestressed concrete beam bridge is likely to craze in operation, which decreases the bridge's safety and durability and then leads to its structure's early failure and destruction.
运营中的大跨径预应力混凝土梁桥箱梁普遍开裂，严重影响了桥梁结构的安全性和耐久性，造成了桥梁过早的失效和破坏。
