The invention discloses a positioning system and method for setting an open caisson foundation in deepwater bare rock, and relates to the technical field of offshore bridge construction, the positioning system comprises a plurality of gravity anchors, a plurality of cable assemblies in one-to-one correspondence with the gravity anchors, and a plurality of cable collecting devices in one-to-one correspondence with the cable assemblies, the multiple gravity anchors are used for being arranged on a bare rock seabed around the open caisson foundation at intervals. The first end of one cable assembly is connected with the corresponding gravity anchor; the multiple cable collecting devices are arranged on the open caisson foundation, and one cable collecting device is connected with the second end of the corresponding cable assembly; and each cable collecting device is used for collecting and releasing the corresponding cable assemblies so as to position the open caisson foundation at the designed position. The anchorage pier does not need to be constructed, the problem that the anchorage pier is difficult to construct in the bare rock environment is effectively solved, the horizontal resistance of the gravity anchor does not change along with the change of the seawater depth, and the problem that the anchorage pier positioning system is insufficient in anchorage pier horizontal rigidity in the deepwater environment is effectively solved.

    本发明公开了一种深水裸岩设置沉井基础的定位系统及方法,涉及海上桥梁施工技术领域,所述定位系统包括:多个重力锚、与多个所述重力锚一一对应的缆绳组件和与多个所述缆绳组件一一对应的收揽装置,多个重力锚用于间隔设置在沉井基础周围的裸岩海床上;一个所述缆绳组件的第一端与对应的所述重力锚连接;多个收揽装置设于沉井基础上,一个所述收揽装置与对应的所述缆绳组件的第二端连接;每个所述收揽装置用于收放对应的所述缆绳组件,以将沉井基础定位于设计位置处。本发明无需施工锚墩,有效解决在裸岩环境下锚墩施工困难的问题,重力锚的水平抗力不随海水深度变化而改变,有效解决锚墩定位系统在深水环境下锚墩水平刚度不足的问题。
