摘要:

以某穿越海堤水平平行顶管工程为例,在施工方案优化分析的基础上,详细地介绍复杂地质条件下长距离大直径水平平行顶管施工技术,并对顶管施工引起的地层变形进行现场监测与分析,提出顶管顶进施工过程中土体扰动特性的变化规律。保证了施工安全与顺利进行,并提出相应的变形控制措施。

Abstract:

The construction technology for level parallel longdistance largediameter pipe jacking under complex geotechnical conditions are descried in detail after optimization analysis of the construction scheme, with a level parallel pipe jacking project as an example. The monitoring resultsof the deformation of the stratum caused by the pipe jacking construction are analyzed. The characteristics of the stratum disturbance during the crossing process is provided.Some countermeasures to control the deformation are recommended and the construction safety is quaranteed.

Key words: large diameter, level parallel pipejacking, crossing embankment, embankment deformation monitoring, embankment deformation control
