一、喷射混凝土厚度控制的重要性随着施工技术的进步和发展,喷锚作为一种新型支护(新奥法重要内容之一),在地下工程中正被日益广泛地采用着。喷射混凝土对峒室结构的稳定极其重要,它封闭围岩节理和裂隙,抑制破碎岩体的位移和变形,起着加固围岩和调动岩体自承能力的作
First, the importance of spraycrete thickness control With the progress and development of construction technology, spray anchor as a new type of support (an important part of the new Austrian law), underground engineering is being increasingly widely used. Sprayed concrete is extremely important to the stability of the cavern structure. It closes the joints and cracks in the surrounding rock and restrain the displacement and deformation of the broken rock mass. It plays the role of reinforcing the surrounding rock and mobilizing the self-supporting capacity of the rock mass
