在饱和软土地基上进行沉桩,由于桩的体积进入土中对软土产生挤压作用,常给附近建(构) 筑物、地下管线产生水平和垂直的位移,严重的会导致产生裂缝或损坏,造成危险,迫使沉桩工作中断,或需采取紧急措施后才能续继施工;对正在施工的邻近桩和桩基会产生水平和垂直的位移,影响荷载的传递和按原设计图纸施工,严重的会影响桩的承载力和建筑物的沉降。随着建设的发展,特别是在城市建设用地紧张的情况下,在密集的建筑群中,经常
Piles are piled on saturated soft soils. As the volume of piles enters the soil, the soft soil is squeezed, often causing horizontal and vertical displacements of nearby buildings (structures) and underground pipelines. Severe cracking may cause cracks. Or damage, resulting in danger, forcing the interruption of the sinking work, or the need for emergency measures to continue the construction; horizontal and vertical displacements will be generated for the adjacent piles and piles under construction, affecting the transmission of the load and construction according to the original design drawings Seriously, it will affect the bearing capacity of piles and the settlement of buildings. With the development of construction, especially in the case of tight urban construction sites, in intensive buildings, often
