primary load meaning in English
主要荷载
Examples
- Based on the modern design theory of tunnels construction that the adjoining rock be regarded as primary load - bearing structure , this thesis have made researches on the stability of tunnels mother rock and the safety of support pattern under the high external waterpressure and high geostress
这就使本隧洞工程的建设面临着极大的挑战。本文是在将围岩作为主要承载结构，支护与围岩共同作用的现代隧洞设计理论的基础上，来研究高外水压力及高地应力下隧洞围岩稳定性及支护结构安全的。 - In addition , this paper carry out successfully the support design practice in the preceding excavation of 4km long exploratory tunnel . according to the thesis research results , the following conclusion can be drawn . if the grouting rock can possess sound anti - seepage capability and the liner structure can hold higher hydraulic permeability relatively , and if the adjoining rock can be made as primary load - bearing structure by construction measure , the stability of country rock and the safety of liner structure will be guaranteed
计算结果表明，如果能使锦屏工程引水隧洞灌浆圈围岩具有较好的防渗性能，将高外水压力控制在灌浆圈以外，再配合透水性相对较好的支护结构以及排水措施，使灌浆圈围岩成为主要承载结构，并使衬砌结构和灌浆圈共同承载，是可以保证围岩的稳定和支护结构安全的。 - Test results show that : ( 1 ) the amount of creep deformation during monotonic primary loading depends on strain rate before creep , creep stress level , and creep time ; ( 2 ) during monotonic primary loading , the stiffness increasing magnificently shortly after creep ; ( 3 ) the direction of creep will change from positive creep ; to neutral creep and negative creep during unloading , while during reloading , it will change from negative , to neutral and positive creep
试验结果表明： ( 1 )在初始加载过程中，经过一定时间蠕变后黏土的强度有很大的提高； ( 2 )在卸载过程中，随应力值下降黏土的蠕变表现出由正蠕变、中性蠕变到负蠕变的逐渐转化； ( 3 )在重复加载过程中，随应力值增加黏土的蠕变表现出由负蠕变、中性蠕变到正蠕变的逐渐转化。
