| 摘 要： | 对斜梁式卸煤沟进行1/10缩尺比例的钢筋混凝土模型试验。分别对其在集中、移动荷载及沟旁堆载作用下的侧向土压力、基底反力分布以及结构荷载-挠度变化规律和结构从开裂到破坏的全过程进行了试验研究。试验表明,斜梁具有弯扭耦合的力学特性,主梁的斜向布置对侧壁和底板的影响较小。 |

| Abstract: | To study the mechanism for skew beam of coal unloading chute, 1/10 scale reinforced concrete mode has been proceeded. The load-deflection curve, earth pressure and distribution of sub-grade contact pressure under concentrated load, moving load and load at the side of the coal unloading chute respectively are obtained and discussed; the whole process from cracking to failure are studied. Experiment shows that the skew beam has the mechanical characteristic of coupling of bending and torsion. The skew beam has little influence on bottom slab and lateral slab. |
