摘要：The ecological safety of buildings and structures built on deformable soils depends largely on the settlement calculation. A classic example of unaccounted influence of differential settlement is the Leaning Tower of Pisa. Its analogues are numerous among the monuments of Russian architecture. The issue of modern builders to exclude the repetition of defects of old masters, who did not have calculating methods of soil mechanics. The accuracy of modern calculations largely depends on the accuracy of engineering investigations’ materials. In the overall assessment of the system's work, the building-base is currently making a large inaccuracy in the incompleteness of survey information, especially definition the location of geological boundaries directly under the foundation. Two examples show the dependency of the geological soil profile inaccuracy on the distance between the wells and it gives a quantitative assessment of the relationship between the magnitude of the inaccuracy and the distance between the drilling wells of geologists. The numerical modeling method shows the influence of such an investigation inaccuracy on the result of the settlement calculation.
