Profession characteristics
Doctoral degree programs are primarily aimed at graduate employment in science and research, which is, among other things, anchored in the objectives of study, learning outcomes and graduate profile. This implies the employment of graduates especially in organizations, institutions and companies that are engaged in research and development activities. These are mainly research organizations whose main activity is research and development, but also construction practice entities, ie companies, where research and development is one of the part of the whole spectrum of activities in addition to commonly realized activities such as production and implementation. A number of implementing companies are currently creating support for their own research and development as they can strengthen their position, competitiveness and marketability in a highly competitive environment. In this regard, there is a growing demand for younger generation professionals with independent creative scientific work, knowledge and insight into new modern trends not only in their expertise but also in related expertise and activities such as PC modeling, simulation, experimental methods and procedures. Last but not least, the graduate has the opportunity to work in the academic sphere, which involves combining scientific research and educational activities. Graduates can thus find employment especially in research organizations and construction practice companies in the context of related development and innovation activities, in educational institutions, especially in the university sphere, which provides them with the possibility of further personal and career development and professional academic growth. Moreover, experience shows that graduates of doctoral study programs are very successful in organizations of the mentioned types not only in the Czech Republic but also abroad, which is also true for graduates in the field of Construction and Transport Structures. Completion of the doctoral study program gives graduates very good prerequisites for employment in, for example, design organizations or state administration in higher professional and managerial positions.

The Mekong River Delta Vietnam and some areas in Ho Chi Minh City where are the areas of sedimentation are deposited originating from rivers and swamps. This is a geologically unfavorable area, the most common foundation soil is the soft soil. Their common feature is the small load capacity and large deformation under the effect of construction loads. Many solutions for soft soil treatment have been applied, but the true nature of soft soil has not been properly assessed in the survey - design - construction so the total settlement and consolidation rate are different. There is a clear difference between theoretical and practical calculations, leading to a number of civil works, roads, etc. Therefore, the study and selection of appropriate technical solutions to soft soil treatment in this area is one of the important and urgent tasks that contribute to improving the efficiency of construction investment in the Mekong Delta Vietnam and some areas in Ho Chi Minh City.
