| 摘 要： | 利用特种中空锚杆兼做注浆管的锚注加固技术,不但充分利用锚杆加固与注浆加固的各自优点,而且还形成其自身所特有的系统“网络”效应,是控制软岩巷道矿压显现的有效手段之一。通过对锚注岩石的扫描电镜分析及实验室和现场的锚杆拉拔试验,系统地研究了锚杆、浆液凝结体等共同形成的网络体系。

| Abstract: | The bolting grouting reinforcement technique where the special hollow bolt is also used as grouting pipe not only makes full use of the advantages of both bolting and grouting, but also forms its unique "network" effect, thus being one of the efficient ways to control the ground pressure behavior of soft rock roadways. Based on the grouted soft rock analysis by scanning electron microscope and both laboratory and on site bolt pulling tests, the network system jointly formed by bolt and grouting coagulum in the bolting grouting reinforcement system is systematically studied. |
