METHOD OF EXCITATION OF SEISMIC VIBRATIONS

摘要

FIELD: geophysics, seismic prospecting. SUBSTANCE: method refers to mechanical excitation of seismic vibrations by actuator (radiator) lowered into hole or another workings, including sedimentations in water reservoirs or marshes. preliminary compaction and hardening of soil are performed in zone close to radiator by pressure of elements of radiator acting directly on soil against walls of hole or working and then seismic vibrations are excited in this zone. Preliminary compaction and hardening of soil are conducted with specific static force sigmac satisfying conduction sigmascp, where sigmas and sigmap are correspondingly limits of elasticity and ultimate strength of soil on site chosen for excitation of vibrations. Later seismic vibrations are excited again in time interval sufficient for re-packing of structure of soil with maximal specific force sigmam which value meets conditions , . EFFECT: improved reliability of method. 2 cl, 3 dwgn
