The karst protection foundations design
The authors analyze the features of the base modeling for the analysis of a foundation in a karst territory, taking the stiffness of the design parameter of the above‐foundation part of the building into account. Advantages of the contact model of a base (the model of the variable coefficient of subgrade reaction) are analyzed. It is proposed to determine the coefficients of subgrade reaction (stiffness of the piles) around the karst cavity with decreasing these coefficients in relation to the same coefficients calculated using standard methods (i.e., without karst deformations). Analytical solutions for different types of foundations are presented. The method for estimating the thickness of an effective karst protection geotechnical screen is proposed.
