由于强夯施工时的震动效应会对周围环境、居民、建(构)筑物等产生不利影响,需采取如应力释放孔、隔震沟等有效措施使其影响降至最低。其中对于隔震沟减震效果的研究目前较多的侧重于隔震沟的深度及数量等方面,而对其形态的研究成果较少。鉴此,本文以某工程实例为依托,通过对直线、外凸、内凹三种不同的隔震沟形态进行测试,探索隔震沟的形态对减震效果的影响。
As the vibration effect during dynamic compaction will adversely affect the surrounding environment, residents, buildings and structures, effective measures such as stress relief holes and seismic isolation ditch shall be adopted to minimize the impact. Among them, the research on the seismic isolation effect of seismic isolation ditch is more focused on the depth and quantity of the seismic isolation trench at present, but less on its morphology. In view of this, based on an engineering example, this paper tests the shape of the isolating groove with straight line, convex and concave to explore the influence of the shape of the isolating ditch on the damping effect.
