摘要
北京地区顶管施工所处的工程条件、环境条件复杂,特别是地层条件差异很大,既有砂性土、黏性土,又有砂砾石、风化岩地层,本文在总结大量工程实践的基础上,介绍了顶管工程在电力隧道中的应用及在北京地质条件下的适用范围,以便为类似工程提供参考依据。
The engineering environmental condition in Beijing is complex for the pipe jacking project,especially for the large difference of the soil layers,there are not only the sandy layer,viscidity layer,but also the grit layer and weathered layer.The paper based on the summarized large engineering practice,introduced the application of pipe jacking technique in electric power tunnel and suitable area under Beijing geological conditions,so as to provide the reference for the similar project.
