摘　　要：盾构的类型确定后,刀盘结构形式与掘进地质的适应性是关系到盾构能否顺利掘进的重要因素之一,根据地质条件确定后的刀盘结构形式在施工现场不容易进行很大改变。本研究根据盾构施工地区地质环境及施工现场情况验证,针对原刀盘在施工中的不足之处,提出优化改造方案,随后,在满足刀盘结构强度与刚度验算的条件下,对刀盘的局部进行现场改造。结果证明,刀盘的现场改造能够进一步提高刀盘对地质的适应性,同时提高盾构施工的效率。The adaptability of the cutter head type to stratum characteristics is one of the most important factors in determining success for shield boring after determination the type of shield. Once parameters of cutter heads are made,it is not easy to change the cutter heads structure on construction site. According to the geological environments and construction condition,and to solve the problem of former cutter head type,the optimization and modification scheme is proposed after checking the structural strength and structural rigidity of cutter heads,and then the local cutter head is modified on construction site. The result shows that the optimization and modification project can increase the geological adaptability and improve the efficiency of shield construction.
