Abstract

The analysis of geotechnical condition for realizing of metro in Ha noi Vietnam is presented in the work. The purpose of the work is to prepare relation problem for building of the first section of underground, to propose a method to minimize the sag of the ground, define the affect of ground strengthen in the sag minimization of the ground, define influence of the proposed method to the state using of the ground for building underground. To propose the conclusions and necessary problem to realize the first section of building underground. To present the necessary reason to build metro in the large cities in Vietnam, in fact mainly is in Hanoi and to propose the method for realization of metro building. Based on the geotechnical parameters of the ground defined by static on the part of the ground \\ill be build metro, it is confirmed that this ground is too weak-Calculation of the carrying capacity and deformation of the weak ground under affect the statical force using infinite beam method, finite element method, and method of norm state terminal carrying capacity. The criterion for estimation of the carrying capacity of the ground is indicated base on the above methods. The mentioned geotechnical parameters are divided by three classes: maximum, average and minimum. The obtained results has indicated that, the range and greatness of the carrying capacity of the ground and it's sag. The method to strengthen the ground is proposed. This strengthen method depends on the deepness and thickness of the weak ground layer. The influence of the strengthening on minimization of carrying terminal capacity and on minimization of deformation of the ground is defined. After strengthing ground, we have used the directive sag method. The executed work to determine a contribution in range of analysis geotechnical condition using directive sag on weak ground and use these methods for strengthening ground.
