| Abstract: | The post-tensioned non-bonded ring-type tendon structure was adopted for the construction of the three sluice tunnels subcontracted by the Fourteenth Hydropower Construction Bureau from the China-Germany-Italy Joint Venture in the construction of the Xiaolangdi Hydro Project. This technique has not yet been widely used so far, but comes to spreading at present in China. This paper gives a brief presentation of its construction workmanship. |
