【摘要】 提出双联系三角形进行竖井联系测量的方法,较单联系三角形联系测量方法不仅提高了精度而且增加了重要的检核条件。对三丝法和双测站法这两种双联系三角形测量方法进行比较表明,三丝法联系测量稳定性较好,使用方便,但占用井筒空间较大,适用于较为宽敞的井筒;双测站法联系测量节省吊垂球线的时间,操作更为方便,对井筒和垂线设备要求不高,但井下空间局限性较大,观测环境也不如井上,在实际的联系测量中可较多采用三丝法联系测量。更多还原

【Abstract】 Double connection triangles method in vertical-shaft connection survey is proposed. Compared with the single connection triangle method, this method not only improves the accuracy but also gives a significant increase in check conditions. Three-wire connection triangle method and double stations connection triangle method are compared with each other to analyze the application from their advantages and disvantages. Three-wire method is often used in spacious shafts because of its good stability, simple operation and conveniences. Double stations method is more time-saving and more convenient to the shaft, but it is often limited by the underground space and circumstances. So the former is more commonly used.更多还原
