水电工程地下洞室石方超挖计量计价的处理方法

Hydropower Station underground Chamber Rock Overbreak Valuation Processing Method

由于水电工程地下工程较多,尤其是抽水蓄能电站,输水系统和厂房一般均布置在地下,地下洞室群更是整个工程的关键线路,且占工程建设投资的比例较大,在地下工程开挖过程中,在规程规范容许范围之外的超挖经常发生,但在石方超挖如何计量与计价两方面发包人和承包人往往存在较大的分歧。本文对如何公平、合理解决这部分超挖的计量与计价问题提出了一些解决争议的方法和思路,以供借鉴和启示。

Because of the large number of underground engineering of hydropower project, especially the pumped storage power station, water system and factory are generally arranged in the ground, underground caverns is the key line to the whole project, and the project construction investment accounted for the proportion of larger, during the excavation of underground engineering, the rules specification outside the allowable range of overbreak occurs frequently, but in rock overbreak how measurement and valuation of two aspects of the employer and the contractor often exist larger differences. How fair, reasonable solve this part measurement of overbreak and pricing problems？ According to the writer＇s many years of practical experience, put forward some method to settle disputes and ideas, for the reference and enlightenment.
