摘　　要：土压盾构掘进下来的渣土,因地层特性(颗粒比重、大小和形状)、盾构机机械性能及施工控制三大原因而不能及时排出,易造成工程项目风险和工程机械故障。通过对滞塞的成因、风险、分类和解决方法进行分析,可对土压盾构渣土滞塞问题从盾构设计、制造和施工三方面提供相应对策。Muck can not be discharged out of excavated chamber of EPB（earth pressure balance） shield immediately due to the following three main reasons： geological characteristics （such as proportion, size and shape of granule）, performance of shield machine and construction operation, etc., and this may cause engineering risk and mechanical failure. By analyzed reason, risk and classification, it can provide related countermeasures against muck blocking in EPB shield project , such as mechanical design, manufacture and construction.
