三峡三期围堰深水硐室爆破药量计算方法探讨

Research on Charge Calculation of Deep-water Chamber Blasting in the 3^(rd) Stage Cofferdam of Three Gorges Project

为计算三峡三期上游RCC围堰药室药量,通过对常用硐室爆破药量计算公式的分析和比较,吸取各公式的合理之处,在露天硐室爆破经典公式的基础上,得出了深水硐室爆破药量计算公式,并应用于三峡三期上游RCC围堰倾倒法爆破拆除设计中。

In order to calculate the chamber charge of the 3^rd stage upriver RCC cofferdam of the Three Gorges Project, some formulas are analyzed and compared,some reasonable factors are used for reference, and a charge calculation formula of deep-water chamber blasting is put forward,which has been applied in the demolishing design of the 3^rd stage cofferdam in Three Gorges Project.
