摘要

在项目的初步规划阶段,DIN 4150-3 标准越来越多地应用于地面建筑,如商业建筑、住宅建筑,特别是文物建筑,这就产生了问题。DIN 4150-3 标准在应用于澳大利亚的情况时经常被错误地解释,这有可能造成长期的后果。将 DIN 4150-3 标准的共振指导值应用于正确的位置(屋顶正下方)需要考虑地基与建筑物屋顶之间的潜在放大效应,而这在澳大利亚似乎并不常见。查阅文献后发现,屋顶振动水平通常是地基振动水平的 1.5 倍,但在实际应用中可能高达 4 到 6 倍,尤其是在文物结构应用中。正确应用 DIN 4150-3 标准会导致地基处的指导值比澳大利亚实际应用中的指导值更为严格,其实际后果要么是施工前进行过多的失效调查,要么是通过增加缓冲距离来限制振动密集型设备,从而增加项目成本和工期。本文提出了一种替代 DIN 4150-3 标准的应用方法,该方法与 BS 7385-2 标准的应用相辅相成,在资产所有者和建筑承包商相互竞争的要求之间为澳大利亚的情况提供了一个合理的折中方案,可适用于所有工业、商业和住宅接收器,包括具有 "遗产 "地位的接收器。

The Increasing Application of DIN 4150-3 for the Assessment of Potential Damage to Buildings from Construction Vibration and its Implications in Australia

The increasing application of DIN 4150-3 to above-ground structures such as commercial, residential and particularly heritage buildings in the preliminary planning stage of projects is problematic. DIN 4150-3 is often incorrectly interpreted when applied to Australian scenarios which has the potential for long-term consequences. Applying the DIN 4150-3 guide values for resonant vibration at the correct location (just below the roof) requires the consideration of potential amplification between the foundation and the roof level of the building, which does not appear to be common practice in Australia. A review of the literature found that roof vibration levels are typically 1.5 times higher than that at the foundation, but in practice can be up to four to six times higher, particularly in heritage structure applications. The correct application of DIN 4150-3 results in more stringent guide values at the foundation than those commonly applied in practice in Australia, the practical consequences of which are either an excessive number of pre-construction dilapidation surveys, or the restriction of vibration-intensive items of plant through increased buffer distances, which increases project costs and timelines. This paper proposes an alternative methodology to the application of DIN 4150-3 that, when complemented with the application of BS 7385-2, provides a sensible compromise for Australian scenarios between the competing requirements of asset owners and construction contractors that can be applied to all industrial, commercial and residential receivers, including those with “heritage” status.
