EVALUATION OF SUBSOIL MASSIF STABILITY TAKING INTO ACCOUNT THE IRREGULARITY OF CONSTITUENT ROCKS ON THE BASIS OF A RANDOM SIZE AND FUNCTION MODEL
Published 2017-03-01“…The use of the random function model when solving the problem of forecasting the stability of the massif enables the evaluation of such important parameters of the safe development of the landslide process as probability of occurrence, i.e. the decrease below the permissible level of the safety coefficient, and the time period of development, so as to maintain the safety status of the massif.A method for determining the cost of maintaining the necessary stability or reliability coefficient value at a time when their calculated values are less than the respective permissible values is shown. …”

Predicting the critical drainage induced by soil seepage failure during pumping in foundation pit construction
Published 2025-01-01“…However, the critical pumping quantity is a key parameter for pumping safety in foundation pit construction and there is no effective method to calculate or test this parameter. Based on Darcy’s law and the equivalent infinitesimal formula, and the formula for calculating the permeability coefficient of pumping tests recommended by the specification for borehole pumping test of hydropower projects (NB/T 35103—2017), this study deduced the expressions of critical pumping quantity of the seepage failure under four conditions, including submersible incomplete hole, submersible integral hole, confined water incomplete hole and confined water integral hole. …”
