强夯对邻近建筑物的影响及消除

Influnce of Forced Ramming on the Neighbour Buildings and Its Elimination

强夯法是近几年发展起来的一种新的处理软地基的有效方法,具有造价低、省工、省料、施工简便等优点。但该法对周围邻近建筑物有振动影响。强夯对周围建筑物的振动影响主要与夯击能量、土壤性质及建筑物构造等因素有关。采用在建筑物周围设“防振沟”的方法可有效地减少强夯对建筑物的振动影响。

The forced ramming is a new effective method used in recent years far treating the soft ground. Such method has the advantages of low operation cost, short period of construction time, materials saving and easy operation etc. But this method can conduct vibration influence on the neighbour buildings. The influeces mainly result from the ramming energy, the soil characters and the building structure etc. Such influences can be reduced effectively by constructing an 'Anti-Vi- bration Trench' around the buildings.
