Abstract Based on the shield construction practices in mixed ground at home and abroad, this paper determines the definition of "hindered mucking" for the first time. In addition to the classification, causes, and risks, it proposes systematic solutions, including reducing large-particle mucks, improving muck workability, and adjusting construction parameters, and presents countermeasures in terms of design, manufacture, and construction of the shield. This paper also provides a reference for countermeasures against hindered mucking regarding new theory, equipment, approach, material, etc.
