Abstract

The study investigates the surface vibrations generated by a new generation, tri-band hydraulic compactor type V8 from Maschinentechnik Schrode AG (MTS), and a reversible plate compactor type DPU 6055 from Wacker Neuson in close proximity to a low-rise residential building. Compaction works were carried out in three stages, at distances: 15 m, 10 m, and 5 m from the building, and at three depths: 0.4 m, 1.2 m, and 1.8–2.0 m. The research was conducted at one measurement point, located on the outer foundation wall of the building, and at three measurement points located on the ground at distances of 1.25–7.5 m from the building. The study analyses the distribution of peak component particle accelerations at the ground, and peak component particle velocities at the foundation wall of the building as a function of the distance of compactors from the building and the depth of compaction works, as well as the mode of work of hydraulic compactor type V8 from MTS. The study contains the comparison of the permissible vibration levels that are recommended by selected European standards (DIN, BS, VSS, and PL) and an approximate assessment of the impact of vibrations on the technical condition of the residential building.

Highlights

The assessment of the impact of vibrations generated in the subsoil, and their transfer to building structures is an important problem of civil engineering
It was assumed that vibrations would be generated by using a new-generation hydraulic compactor type V8 from Maschinentechnik Schrode AG (MTS) integrated with an excavator, and a reversible plate compactor-type

Summary

Introduction

The assessment of the impact of vibrations generated in the subsoil, and their transfer to building structures is an important problem of civil engineering. This issue is currently the subject of frequent studies and analyses concerning mainly urban areas. Articles regarding vibrations that are caused by the work of construction machines are an important collection of materials on this matter. Vibrations of high intensity are induced when driving foundation piles [5,6], which very often makes the use of this technology unacceptable in close vicinity to buildings. Significant values of acceleration or vibration velocities are generated during driving and pulling out of sheet pilings [7,8]. The influence of vibrations spreading in the environment can be very important, which is why methods for their reduction are sought out so often [9,10,11,12]
