“…When the injection pressure reaches a certain critical value, it causes thesoil hydraulic fracturing, and the mortar begins to spread to the sides along the formed paths (cracks) in the soil. To retain and accumulate the largest volume of cement mortar in the injection zone, as it is supply into the soil mass, it is necessary to smoothly increase the pressure to the required value without sudden jumps [13][14][15][16][17].…”

Studies of the piles bearing capacity after strengthening soil by cement mortar pressure injection were carried out to determine pile foundations bearing capacity increasing patterns in a result of soils cementation. Depending from the volume and cement mortar technological injection parameters, the soil stress state around the pile changes, additional pile-soil compression occurs and the friction along the lateral surface increase, as well as the soil resistance under the pile bottom end. Cementation effect on the pile bearing capacity for different injectors location and the number of piles in the foundation were determined by tests. The research results can be used in the pile foundations reinforcement design in conditions of reconstruction with increasing loads on the foundations.

The construction of buildings and structures in seismically hazardous areas is closely connected with the solution of the question of the dynamic stability of the soil base. World experience shows that the most destructive effect of seismic action is dynamic liquefaction. The probability of occurrence and intensity of this process are determined by the geological and hydrogeological structure of the soil massif. Based on the results of special laboratory and field dynamic tests of soils, it is not always possible to completely exclude the possibility of developing this extremely negative process. In this paper, the main stages of the analysis of the dynamic stability of the soil of the foundations of buildings and structures in complex engineering-geological conditions are presented. A brief review of existing domestic and foreign measures for the protection of buildings and structures from the dynamic dilution of soils is given. Information is provided on the applicability and comparative effectiveness of the methods in question.

“…Creep and relaxation, a decrease in strength under prolonged action of loads are all manifestations of the rheological properties of soils. Without taking into account rheology, the solution of the main problems of soil mechanics is not possible [20][21][22][23][24][25].…”

One of the main issues in the design of foundations is the correct forecast of the development of long-term deformations (settlement) of the foundations. Among the main factors affecting settlement, one can single out the neglect of changes in the rheological parameters of the soil in time and the neglect of the loading regime, as well as the processes of soil hardening in time. The work presents the results of a study of the behaviour of samples of clayey soil with a disturbed structure under conditions of triaxial cyclic loading, taking into account the strengthening effect. The relevance of the problem of studying the hardening process is associated with the assessment of the deformability and strength of clays with rheological properties. The tests were carried out in a pneumatic stabilimeter with an artificial soil created of paste. After preparing the samples, they were placed in a sealed container until the start of the test for a period of 1 to 5 days. To establish the ultimate strength of the soil, single static loads were carried out at a given value of the uniform pressure. The main control characteristics during the tests were the maximum and minimum values of the cycle voltages. If the sample did not fail during cyclic loading, it was destroyed by a stepped increase in the static load. The dependences of the change in the strength of a clay soil sample during the holding time before the start of the test were obtained at various values of all-round compression and the amplitude of the cycle. The strength of the soil with a change in the holding time increased up to 1.27 times.
