高强混凝土在立井井壁中的应用及展望

高强混凝土是一种品质优良的建筑材料，具有强度高、变形小、良好的抗渗性和抗冻性。将高强混凝土用于深厚表土层立井井筒工程中，能满足我国不断加深的钻井和冻结井简建设的需要。高强混凝土复合井壁具有减小井壁厚度，防止井壁渗水，降低建井成本的优点。介绍了我国煤矿立井使用高强混凝土所取得的经验，提出了今后深厚表土层中高强混凝土复合井壁的结构形式，以便更好地推广和应用高强混凝土井壁，解决深厚表土层立井支护的难题。

APPLICATION AND EXPECTATION OF HIGH STRENGTH CONCRETE IN SHAFT LINING

High strenght concrete is a kind of good quality architecture material,which has high strength,litter distortion and a penetrating-resistant character as well as a frost-resistant character.The use of high strength concrete in shaft lining of depth soil might meet with the constructive need of frozen and boring shafts.The high strength concrete composite shaft lining has excellent qualities of decreasing thickness,infiltration and cost in building shafts.In this paper,the experience obtained in making use of high strength concrete of Chinese mine shaft lining is introduced.The future composite shaft lining of high strength concrete structure forms have been suggested in order to be widely use of them and to solve the difficulty problem on supporting in depth soil shaft linings.
