预压应力 meaning in Chinese
compressive pre stress
compressive pre-stress
Examples
- Aiming at the drilling defects in engineering ceramics , drilling with compressive pre - stress is proposed
针对工程陶瓷的孔加工缺陷，提出了预压应力钻削法以改善其入、出口的加工质量。 - In view of cost , practicability and maneuverability , the special sintering diamond trepanning drill was developed for drilling ceramic composite components originally
根据复合构件加工中的各种缺陷，分析了采用预压应力钻削对改善表面加工质量的重要性。 - 6 ) horizontal braces force of horizon that results from tension . therefore , it reduces pre - compress stress . horizontal braces is stronger , it ' s influence is more important
（ 6 ）横向约束的存在减弱了张拉在框架梁中形成的轴向力，从而减小在框架梁中预压应力，横向约束越强，它的影响就越大。 - In this test , a special bolt - jack is used to exent of prestressing force to brace angles as the whole structure is under dead - load . in this state brace angles withstand partly load before twice - load and the stress and strain of concrete are decreased . in this way the aim of removal of load and strengthening can be reached
本试验中采用专用螺栓千斤顶在恒定荷载水平下对混凝土柱角钢撑杆施加预压应力，使外包角钢在二次受力前即分担部分荷载，使混凝土应力水平和应变水平降低，达到卸载与加固同步进行的目的。 - This thesis aims to analyze how to select and assign prestressed tendon , how to design anchorage bearing joint , how to control the crack , how to calculate the axial prestressed force and the third moment and how to design the edge column of top layer . on the base of the research in and out our country and construction of the prestressed structure , some helpful conclusion and suggestion are presented , which is suggestive for the design and construction of long span continuous prestressed concrete frame
本文将综合设计与施工两个方面，对预应力筋的选用、布置，锚固区的设计及构造处理，裂缝问题，侧向约束对梁轴向预压应力及柱中第三弯矩的影响，顶层大跨边柱设计等几个问题进行系统的分析研究，并在国内外研究和大量工程实践的基础上，提出了一些建议和预防措施，对此类工程设计和施工有一定的参考价值。
