摘    要:
研究了3种模型的试验梁:孔道完全压浆、孔道内某一段长度未压浆和孔道完全未压浆,以探索孔道密实程度不同对预应力混凝土梁变形的影响。试验结果表明:孔道压浆不密实与未压浆梁的开裂荷载比压浆密实的梁低,孔道未压浆的梁比孔道压浆不密实及压浆密实的梁挠度大。

关 键 词:孔道密实程度  试验研究  变形  影响

Abstract:
The paper explains study on experimental beams of three models, such as pore fully grouted,pore within a certain period of non-grouted length and pore no grouted,in order to explore the different levels of pore-compacting of the deformation of prestressed concrete beams. The results showed that the cracking load of not compacting grouting and non-grouting beam was lower than the compacting grouting beam.The deflection of non-grouting beam was large than the non-compacting grouting and non-grouting beam.
Keywords:the degree of pore-compacting  experimental research  deformation  impact
