容许拉应力 meaning in English
allowable tensile stress
Examples
- Allowable tensile stress
容许拉应力 - In harsh climate region , mere exists obvious local stress concentration near the upstream and downstream of the exposed - in - winter horizontal surface of the rcc dam , and the surface of spillway bucket though heat insulation is applied on the surfaces , tensile stress still exceeds the allowable one of concrete . this paper puts forward to adopt preset crack to avoid occurring more cracks . the special crack model is applied to simulate the dam preset crack , and the joint model of fracture mechanics is induced into strain - soften model
在结构措施方面，针对严寒地区高碾压混凝土重力坝坝体越冬层面的上、下游面附近及溢流坝堰面反弧段表面有明显的局部应力集中象现，在已采取一定的表面保温防护的条件下，拉应力仍然超过混凝土容许拉应力，开裂难以避免，进而提出设置碾压混凝土坝表面预留缝结构措施并对该措施进行深入研究，包括预留缝的扩展稳定和坝体沿预留缝的稳定性，以避免大坝在无措施部位开裂，解决大坝越冬层面水平施工缝的开裂问题。
