| Abstract: | A caisson tunnel had complicated design section of foundation trench, high accuracy of foundation excavation, tight schedule, great difficulty in excavation in slightly weathered rock, and high-standard inspection.To address these technical difficulties and based on this caisson tunnel, the excavation method in rock foundation and the construction scheme are discussed in detail.According to the project scale, geological characteristics and the surrounding environment, the method of foundation excavation under the water is determined through the principles, advantages and disadvantages, the applicable range, and the main parameters of each method.Also, announcements of the excavation method for foundation trench are given.Research results have certain reference to the similar rock foundation excavations under water. |
