随着H型钢排桩和型钢水泥土搅拌墙(SMW工法)内撑支护体系的广泛运用,中穿H型钢混凝土冠梁引起的工程问题日益突显。从工程现场及工程设计两个方面入手,研究中穿H型钢混凝土冠梁在工程应用过程中存在的问题,进而提出相应的建议,对确保工程安全及完善中穿H型钢混凝土冠梁设计方法具有重要意义。 With the extensive application of the internal support system of H-shaped steel piles and steel reinforced concrete mixing walls (SMW method), the engineering problems caused by the wear of H-shaped steel concrete crown beams have become increasingly prominent. Starting from engineering site and engineering design, the problems existing in the process of engineering application of H-shaped steel reinforced concrete crown beam are studied, and then some suggestions are put forward to ensure the project safety and improve the design method of H- Significance.
