The seismograph is a kind of seismic prospecting instrument, detection zone is nearly hundreds of meters. Along with the digital technology application in the engineering seismograph, need to collect and transfer a large of data, and efficient data transmission is directly related to exploration efficiency. Therefore, this paper proposes a parallel data concentrator based on the technology of FPGA,...
The MEMS acceleration sensors have been widely applied in many fields, especially in the detection of geological and geological imaging. In this paper, on the basis of MEMS sensors designed the sensor peripheral circuit and the signal conditioning circuit. The theoretical simulation and experimental test are adopted to carry out the shallow geological exploration project. Experimental results show...
Present paper deals with the computing of passive earth pressure acting on the vertical rigid retaining wall supporting the soil mass subjected to water seepage. The basic assumptions of Coulomb’s theory and the 2-dimensional steady flow function are used. Three Coulomb-type solutions for the passive earth pressures are presented for the walls provided with three different drainage systems respectively...
