| 摘 要： | 通过对试验梁的弯曲裂缝及剪切裂缝采用低压低速灌浆法（壁可法）修补再加压试验，研究该法的裂缝修补效果。结果表明，修补后继续加压，原裂缝直到梁最终破坏再未开展，修补效果较好。提出应用壁可法应注意的一些问题，尤其是对化学组分的初凝、终凝时间的控制。

| Abstract: | In this paper, experiment beam raised pressure after repaired proved having a good effect. Summarizing some questions that should be pay attention to in using the low speed and low pressure grouting （BICS）. Until the beam destroyed and had not launched and then finally original crack, it is better to mend the result. Especially the control the starting coagulation and ending coagulation of chemical composition. |
