摘要: 针对冲击成孔在城市施工引起的振动问题,主要考虑附近人群对振动强度的接受程度因素,在剖析国内外相关规范及标准的基础上,提出了人和建筑物可接受的控制标准。冲击施工过程中,对相邻建筑物进行了多方位的振动监测,同时对附近人群进行了调查记录,验证了标准的合理性,使该工程得以正常施工,达到了预期的效果。

Abstract: The vibration caused by percussion boring in urban area will affect the people in surrounding areas. Taking the acceptable vibration degree into consideration, a control standard acceptable for people and buildings is proposed based on domestic and international specifications and standards. Monitoring of the vibration in different aspects was made for the adjacent buildings, and the people nearby were investigated as well. The standard was proved to be reasonable in controlling the vibration so that the construction of the project can be carried out and the plan can be achieved.

Key words: mechanical percussion boring cast-in-situ pile construction , vibration of the percussion , building, people’s feelings, particle vibration velocity , standard of bearable vibration
