我们在1959年大量修建干砌中、小型石拱桥中,取得了很大的成就,在这个基础上,今年又建成一座三孔连续式干砌石拱桥(图1),扩大了干砌石拱桥的应用范围,为大量节约水泥、技工和运力开辟了新途径。 这座桥是悬链式等截面实腹石拱桥。净跨为90米,拱度为1/4,拱环厚度为0.7米,全长82米。依浆砌拱桥的设计建造。拱环用 In 1959, we built a large number of middle and small-scale stone arch bridges and achieved great successes. On this basis, this year we built a three-hole continuous dry stone arch bridge (Fig. 1), expanding the dry stone arch bridges. The scope of application opens up new avenues for substantial savings in cement, mechanics and capacity. This bridge is a catenary solid arch bridge with equal section cross section. The net span is 90 meters, the crown is 1/4, the arch thickness is 0.7 meters, and the total length is 82 meters. Slurry arch bridge design and construction. Arch ring
