为了观察衬砌和不衬砌隧洞以及埋藏式高压管道的工作状态,早在六十年代初期,我国就在多种不同地质条件下进行了不少的圆形岩洞水压试验。采用的衬砌材料有薄钢板、预制混凝土块、现场浇筑的混凝土或钢筋混凝土,以及喷射混凝土。在各级加载和卸载的循环下,都记录了经向引伸仪、应变计和渗压计的读数。本文评价了在花岗闪长岩和闪长岩中进行的三个岩洞水压试验的成果。 In order to observe the working conditions of lining and non-lining tunnels and buried high-pressure pipes, as early as the early 1960s, many circular cave pressure tests were carried out in many different geological conditions. The lining materials used are thin steel plates, precast concrete blocks, cast-in-place concrete or reinforced concrete, and shotcrete. Readings of the warp extensometer, strain gage and osmometer were recorded at all levels of loading and unloading cycles. This paper assesses the results of three cave hydrostatic tests conducted in granodiorite and diorite.
