摘要
给出选择盾构工法的准则及避免盾构工法施工事故的措施。指出盾构隧道施工成败的关键是正确地选定盾构工法，而决定盾构工法的关键是准确可靠的土质条件的调查。此外，覆盖土的厚度、隧道线形、掘进距离、工期、竖井用地、邻近构造物等调查也至关重要。文中还就施工中易引起事故的土质问题、邻近施工问题。
The rules to select the shield method and the handle to avoid the accidents during the constructing are developed in this paper. It shows that the key of the settlement of the shield tunneling construction lies in the correct selection of the shield method, in turn the key of the determination of the shield method lies in the correct survey of the soil condition. Besides, it points out that it is also important to survey the cover coat thickness, the tunnel line shape, the dig in distance, the working time, the occupied coat for the hold up well and neighboring building. Finally, the handle to avoid the accidents during the constructing owing to the problem resulted from the soil and neighbouring constructing are provided respectively in this paper.
