查询词典 concrete

The rigidity of concrete structure below the roof、abutment rigidity of arch foot and sunshine radiation are analyzed as factors of temperature action in roof structure. It shows that the rigidity of concrete structure has little effect on temperature action, but the rigidity of arch foot affects temperature action more and is the determinant that assures the arch mechanic behavior .The analysis result also shows sunshine radiation should not be neglected.

、料斗网上不应堆满混凝土，对网上的超粒径骨料及杂物要及时清除，当料斗内的搅拌轴被卡死不转时，要暂停泵送，并及时反转操作，排除故障，料斗中的混凝土不能太少，以防止因吸空而导致管路堵塞，当供料跟不上时，要及时停止泵送。

The anchor anchoring depths could be regard as critical value for concrete edge failure and anchor failure. When the anchor edge distance was shorter than anchor anchoring depth, the failure mode was concrete edge failure and anchor space length had some influence on cracking load. When anchor space length was longer than anchor anchoring depth, the failure mode was anchor failure.

锚栓的锚固深度可以认为是混凝土边缘破坏以及锚栓破坏的临界边距，对于锚栓边距较小的情况，以混凝土边缘破坏时的承载力为标准，锚栓间距对于试验的开裂荷载有影响；对于锚栓边距较大的情况，以锚栓的破坏为标准。
