Tiivistelmä
The study was commissioned by Finnish Consulting Group Oy. The purpose of this thesis is to facilitate the implementation of dry deep mixing (DDM) technology into Russian excavation support design and construction practices, and answer the questions of deep mixing technology design.
The aims of the research were to study the DDM method and compare it with ground improvement methods used in Russia nowadays; show the advantages of DDM to be used in Russia particularly in St. Petersburg; examine general and legal aspects to use DDM in Russia.
The thesis should be of interest to engineers and technologists working in the fields of deep soil excavations and the improvement of soft soil foundations to support heavy loads
The first part of thesis contains a description of the individual methods of ground improvement focusing on the equipment, the procedures, and the properties of the treated soil.
The bulk of the thesis consists of the more detail description of the DDM method including applications, materials, design principle, equipment, construction, execution, quality control and quality assurance and documentation.
The thesis continues by depicting the positive aspects of the usage of DDM in Russia. This part indicates the main advantages of DDM and its useful properties for improving difficult sick soils in St. Petersburg. Also geotechnical problems of St. Petersburg are discussed in more detail.
In the last part there is information about the possibilities of using DDM in Russia, about the availability of required materials and equipment. There is a list of some cement and lime plants near St. Petersburg. There are also the information about quality control in Russia, about problems in survey branch, and a list of the biggest organizations, which implement quality control.
The results of this work can be applied to using DDM in Russia for improving the permeability, strength and deformation properties of soils as a cost effective and environmentally sound method.
