Intensive Technology of Construction of Geotechnical Structures in Transport

Abstract

The scientific basis for the intensive technology of increasing the foundation and geotechnical structures stability on the massive layers of weak soils is outlined. The authors have this technology patented. It is intended for the construction of railways and highways in swampy and waterlogged areas. The stages and principles of intensive technology are described. The content and order of strengthening the weak base are considered. The effectiveness of the technological regulations application for strengthening the weak formation basis on the M-11 Moscow—St. Petersburg Highway is determined and the experience of this application is summarized. Intensive technology for strengthening the weak bases is implemented in conjunction with geotechnical research methods. The necessity of technological management of the construction machines operation modes in order to improve the strength characteristics of soils is shown. The solution is made using the finite element method (FEM). Technological management methods have been developed for maximum allowable loads. The conclusions presented in this article were made using the results of the weak basis hardening processes experimental study which took place in the experimental areas of geotechnical construction.
