A method of acquiring seismic data (1000) comprises: positioning (1100) a plurality of sensors to record microseismic signals in a predetermined observation area comprising a study volume with a plurality of study points; recording (1200) microseismic signals in the predetermined area, the microseismic signals comprising waves with a vertical component and a horizontal component; processing (1300, 2300, 3300) the recorded microseismic signals; a first modeling step (1400, 4400) for calculating expected vertical components in the predetermined area; generating (1500) a predicted subsurface earth structure by comparing the recorded and processed microseismic signals to the calculated expected vertical components in the predetermined area; a second modeling step (1600, 5600) for modeling seismic-mechanical properties for the predetermined observation area based on prior data; simulating (1700) expected microseismic responses on sensors from the study points of the study volume; locating (1800) a microseismic event; determining (1900) the type of the microseismic event and the corresponding moment tensor in the study volume using a maximum likelihood method; calculating (2000) a moment magnitude of the event; and comparing (2100, 6100) of microseismic events at different points in time to obtain a temporal resolution of the change in seismic activity.

This invention provides a sustainable and environmentally friendly consolidating material that can be supplied stably and does not cause environmental problems such as environmental pollution or increased carbon dioxide emissions, thereby enabling not only carbon neutrality but also carbon negativity, as well as a method for constructing soil structures and a ground improvement method using this material. [Solution] This solidifying material is mainly composed of silica-containing combustion products, which are obtained by partially burning and cooling land-derived waste and contain SiO2 and carbon as active ingredients. The amorphous silica in the silica-containing combustion products undergoes a hydration reaction and solidifies, thereby enabling carbon negativity.

This invention discloses a biomimetic structure-based support design method and an accelerator magnet support. The method includes: constructing modal and strength indices based on user requirements; confirming the structural form considering high stiffness characteristics and performing biomimetic design of the support to obtain a support design model; performing modal and strength analyses on the support design model to obtain analysis results; comparing the analysis results with the modal and strength indices, and outputting the support design model based on the comparison results. The accelerator magnet support includes: a honeycomb structure on the top plate; an animal skeleton structure for the side support structure; a layered honeycomb structure for the middle side plate; a diatomaceous earth structure for the bottom crossbeam; a tree branch structure for the cross supports; and a plankton-inspired outer shell. By using this invention, the weight of the support can be reduced while minimizing the impact of ground vibration. This invention can be widely applied in the field of support design.
