摘要：The stability of block stones is usually studied based on flat-bottomed condition, while most of time they are used on slant breakwater. Empirical formula computation and physical model test method which are in common use were adopted to research the stability of block stone on a coal-fired electricity station engineering in Indonesia. By means of a 1/40 scale physical model, the critical stable weight of block stones and bottom stones of breakwater is confirmed during different flow dynamic and water level. Additionally, it is demonstrated that the section design of breakwater in the project is reasonable and the determinant standard on the stability of block stone under the current action is put forward. Through practical experiment, this paper verifies the formula shortcomings that don't consider the angular correction and water level in exiting specification. Studies have found that firstly, the calculating results of Technical Code of Regulation Works for Navigation Channel and C.B.И3бaш are close in all formulas. Therefore it should be applied before the test and among the correlated design. Secondly, by comparing the empirical formula and physical model, the last one is recommended in the analogous research.
