“…The construction of the underground part of any structure requires the special attention of [1][2][3][4][5][6][7][8][9] geologists. Any introduction of structural elements into the base, as well as extraction of soil from it, alters the stress-strain state of the base (SSS) that has developed over a long geological period.…”

Along with other advanced geotechnical technologies for the exploration of underground space, electro-discharge technology (EDT technology) is one of the fundamental in the field of the construction of auger-injection microcircuits, as well as the construction transformation of the properties of foundation soils with weak physical and mechanical characteristics. At the same time, having significant differences compared to other methods of subsurface development of buildings and structures, the geotechnical EDT technology has a number of advantages, such as: 1) increased specific soil load-bearing capacity; 2) constructability of the auger piles in any geotechnical conditions; 3) possibility of geotechnical works performance under restricted conditions. As a basic structure for the development of new technologies, it has a large scientific research potential for the purposes of introducing it into modern underground construction.

The use of the technology of high-frequency sheet piles driving or extraction in conditions of weak, structurally unstable soils inevitably leads to a change in the structure of the soil. This is especially true for buildings which fall into the zone of influence. Often, foundation for historical buildings is water-saturated sands, spread by fluid and fluid-plastic clay soils. In the process of external dynamic action, the soil foundation is been destructing, so their strength and deformation parameters are reduced. In this case, the result of vibration effects on a dispersed water-saturated sample can be both compaction for sandy soil and decompaction of clay soils. These changes lead to additional deformations of buildings and structures of the surrounding area. Therefore, the issue of assessing the limits of applicability of vibration technology in certain conditions is relevant. The object of the study is the changes in the properties of clay soils of various consistencies after exposure to vibration. The results of laboratory studies to determine the strength parameters of dispersed soils after high-frequency vibration are presented. The results of field measurements by CPT "before", "after" vibration immersion and vibration extraction of sheet piles are considered. Comparison of the results of field and laboratory studies is carried out to identify patterns of change in the strength characteristics of weak soils under the influence of vibration loads. A tendency towards a decrease in the strength parameters of dispersed soils is shown. Currently, due to the insufficient number of laboratory and field studies to study the effect of high-frequency vibration on the change in the strength parameters of weak water-saturated clay soils, it is not possible to identify a clear dependence of the change in parameters on the time and frequency of vibration.

“…First one is the shear waves, which called S-waves, it generated along the contact surface the sheet pile with the surrounding soil due to the relative motion between the sheet pile and the surrounding soil. The sheet pile driven vertically to the soil, which produces compression waves [10][11][12][13][14][15][16][17]. The S-waves spread out from the sheet pile shaft on a conical wave front as shown in Figure 1 [18].…”

Construction vibration such as sheet pile driving can produce earthborn vibrations which may be leads to problems for the supporting soils and adjacent structures. Vibrations create the stress waves traveling outward from the source through the soil and cause structural damage due to dynamic vibration induced settlement. The main aim of the present research is to study the vibration effect through sheet pile driving technique on the surrounding soil and adjacent structure. A series of plain strain finite element analysis using Plaxis 8.2 dynamic module is run to simulate the installation technique of a sheet pile unit using driving technique (hammer type). The effect of construction stages with different embedded sheet pile depth, sand relative density, and foundation distance from the driving source is also studied. The influence of hammer driving amplitude on the foundation response and excess pore water pressure are presented. The results showed that the increase of both embedment sheet pile depth and hammer efficiency can significantly produce higher excess pore water pressure and foundation settlement. The increase of sand density can also has a great effect in increasing the foundation damage of adjacent structure compared with low sand relative density. The building damage can significantly take place when the driving is closed to foundation.
