试验员考试题库《5》（Test questions bank 5） 1. how is the quality grade of the sub project assessed? (1) calculation of grading value of divisional project; In sub project, the weight of the general sub item is 1, and the weight of the main (main) sub item is 2. (2) evaluation of quality grade of sub project The various sub projects are all qualified, the weighted average score of 85 points or more, and the main sub projects were all evaluated as excellent, the division of Engineering awarded the excellent project; if all qualified, but the weighted average score of 85 points or below, although the weighted average in 85 points and on. But the main project not all reach the standard of excellence, the division of engineering as qualified as engineering; not all reached the standards, the project is not qualified. 2. semi rigid base, the acceptance should detect what content? And their respective detection methods are described. (1) there are 7 items to be tested: compactness, smoothness, thickness, vertical height and width, Cross slope and strength. (2) the corresponding detection method: sand filling method (or cutting ring, bag method), 3M method, level ruler method, measuring method, digging or drilling method (general method and compaction test together) level method, static compaction method (field sampling, indoor specimen) 3. test the main points of sand filling test. 4.1) indoor calibration (1) the quality of M cone in the cone of the lower cone of the sand filling tank is calibrated by the glass plate, and the error is not more than 1G by three calibration; (2) measure the unit quality of sand by calibrating tank mark. 2) field testing (1) select the test site and clean it; (2) when the surface is rough, determine the amount of sand used to fill the rough surface and the concave convex surface; (3) try to dig holes, and the diameter of sand filling tube uniform hole, test hole depth should be equal to the determination of layer thickness, wall should be straight; (4
