| 5. | When this kind of stress and strain over allowable of concrete , it willing produce crack and cause construction strength to lower and enduring ability to die 当这种拉应力和拉应变超过混凝土的允许承受能力时,混凝土将产生开裂和引起结构的强度降低和耐久能力的减弱。 |
| 6. | Considering the randomness of strength and deformation of concrete material , a mathematic approach of producing random variables series of concrete ultimate tensile strain is proposed 摘要针对混凝土构件材料强度和变形性质的随机性,采用数学方法提出构造混凝土极限拉应变数列的原理。 |
| 7. | But this kind of constringency transform because of its inner part not even stress and all control functions exist with exterior , and make concrete produce to pull - stress and pull - strain 而这种收缩变形又由于其内部应力不均和外部约束作用的存在,使混凝土产生过大的拉应力和拉应变。 |
| 8. | The study proved that tensile strain arose firstly in the outer shaft wall after it ' s building , then decreased gradually with decreasing of temperature , finally , it converted to compressive strain 研究表明:外层井壁浇筑后,混凝土首先产生拉应变,而后随井壁温度下降而逐渐减小并转变为压应变。 |
| 9. | But be the concrete to transform the stipulation ( repress , bar ) function , then want the companion to living to pull in response to the dint with pull to adapt to changes 混凝土随着温度、湿度的变化要伴生胀缩变形。而当混凝土的收缩变形受到约束(抑制、阻碍)作用时,则要伴生拉应力和拉应变。 |
| 10. | Based on the analysis result , an experimental system was established using 5 special concrete embedment strain sensors at a highway , and the experiments were carried on 在此分析的基础上,建立了实测移动车载下的路面板底拉应变响应的方法,并用5个特殊的混凝土埋入式应变传感器在高速公路上建立了实测试验环境进行实测试验。 |
