| 摘 要： | 本文介绍利用对比实验方法 ,研究具有不同形式裂缝的混凝土构件在化学灌浆后的力学性能改善情况。正截面试件 ,裂缝灌浆后刚度略有提高 ,但极限承载力无明显变化。斜截面试件 ,当临界斜裂缝未出现时裂缝灌浆后极限承载力无明显变化 ;当临界斜裂缝出现后裂缝灌浆极限承载力明显提高。

| Abstract: | In this article,authors present the test results,using the contrast experiment method,that chemistry grouting improved the mechanics capability of the concrete member with different form crack.In bending failure test pieces,after crack chemistry grouting,the bending rigidity slightly has increased,but the limit load-carrying capacity has no obvious variety.In shear failure test pieces,crack chemistry grouting before the critical diagonal crack appear,the limit load-carrying capacity has no obvious variety;crack chemistry grouting after the critical diagonal crack appear,the limit load-carrying capacity have obvious improvement. |
