The circular tube groutingtest was made by the established model of grouting slurry tube in rock mass and using piston type grouting pump commonly used in grouting engineering.
通过建立岩体中灌浆管状模型，利用灌浆施工中常用的活塞式灌浆泵，进行了圆管模型灌水(浆)试验。

The water pressure test after adopting cement grouting proves, although the permeability of rock improves, it can not achieve the design requirement.
采用水泥灌浆后所做的压水试验证明，岩土的渗透性能虽然得到改善，但是达不到设计要求。
