1) lacing wires crackles
拉筋开裂
1.
It is said that,since around the LP fourth stage blades nz-12～+15% binodal and trinodal curves had torsional oscillations,and the lacing wires and lacing poles were not clean before welding,with welding silver brazing were more and more there,which caused the lacing wires crackles,lacing wires silver brazing breaking down and other most blades tangential A0 static frequency unqualified.
对某发电厂1号汽轮机低压第4级叶片拉筋大面积银焊脱落,脱焊、拉筋开裂及绝大多数叶片组切向A0静频率不合格的原因作了分析,指出:低压第4级叶片本身存在nz附近-12～+15%有双节线、三节线扭振的共振因素,加之由于拉筋与拉筋孔清理不干净,反复施焊,问题愈积愈深,银焊愈堆愈多,致使问题的发生,文中提出了处理方案并实施。
2) Preventing crack tie bar
防裂拉筋
3) stiffener crack
筋条开裂
4) cracking tensile stress
开裂拉应力
5) tensile-shear mixed mode fracture
拉剪混合型开裂
1.
The tensile-shear mixed mode fracture of quasi-brittle materials such as concrete and rock is analyzed by fixed and rotating smeared-crack models based on the deformable distinct element method.
基于变形体离散单元法,采用固定和旋转的弥散裂缝模型,分析了混凝土、岩石等准脆性材料的拉剪混合型开裂行为,给出了开裂准则以及裂缝扩展机制,初步探讨了从连续介质到非连续介质转化的数值模拟。
6) reinforcement

拉筋
1.
The Drucker-Prager Model is chosen to simulate the non-linearity of soil,the distribution law of the lateral earth pressures on the facing and tensile force of the reinforcements are analyzed and studied.
结合某公路扩建工程中采用的双面加筋挡土墙结构,采用有限元法对该挡土墙的受力特性进行数值模拟分析,计算中采用Drucker-Prager模型模拟土体材料的非线性,研究分析拉筋拉力及墙背侧向土压力的分布规律,有限元分析结果与现场测试值具有较好的一致性,分析成果对该挡土墙的推广应用提供了重要的参考价值。
2.
By the prototype testing study on the mechanical characteristics of the wall, the change and distribution law of the reinforcement tensions, the lateral earth pressure on the face, the vertical earth pressures at the base were obtained.
6m的双面加筋挡土墙首次应用于山区高等级公路扩建工程中,通过对该挡土墙施土阶段受力特性的原型测试研究,得到了拉筋拉力、墙面板所受土压力、基底应力随填土厚度的变化和分布规律,研究成果可供今后设计和施工类似支挡结构时提供参考。
