顶管施工引起土体变形机理分析

Mechanism analysis on soil deformation resulted from pipe jacking construction

从顶管施工的整个施工工艺过程出发,详细分析了顶管施工引起地面沉降的变形机理,找出引起地面变形的相关因素,并指出顶管施工对土体扰动最大的位置应在开挖工作面及以后的位置。

The author commences on the whole construction technology process of the pipe jacking construction, analyzes the deformation mechanism of the earth settlement resulted from pipe jacking construction in detail, finds out the corresponding factors of leading to earth deformation, and points out that the largest position of the soil disturbance from the pipe jacking construction is on the excavation work face and position after that.
