20 days, "Informal discussion of Chengdu earthquake lifeline " hold in Chengdu, short of Wenshui River of spot experiment imitate plain seismic physics principle

Informal discussion spot

Yesterday, by American civil engineering rock of society, China is mechanical sponsor jointly with engineering meeting " informal discussion of Chengdu earthquake lifeline " in southwest of the iron in Chengdu scientific academy is held smoothly, come from Sino-US authoritative and geological expert, shake of on the spot is forecasted, monitor, and the rehabilitate of the lifeline system such as the communication after the earthquake, traffic, electric power, rebuild the problem undertakes delibrate. University of Chinese mining industry (Beijing) mechanical with construction project prexy He Manchao spot demonstrated experiment of trends of imitate of physics of earthquake of plain of short of Wenshui River, think to be able to divide separate out earthquake through imitate experiment the law that curve of motion of header board piece has scarcely common, after believing, forecast through the earthquake, the development of the system that monitor and perfect, the instrument that monitor is put in corresponding fault, relatively accurate forecast can be carried out successfully before the earthquake.

   Hopeful of the new generation appearance that monitor is born after a month

After shake of earth of plain of short of Wenshui River, he Manchao and his project group did test of imitate of physics of earthquake of a plain of short of Wenshui River, study the earthquake may be forecasted. On the informal discussion yesterday, he demonstrated imitate experiment through computer spot. Demonstrating animation to go up, two of mountain range of dragon door mountain board piece athletic curve is very active, two motion curve is centered ceaselessly as time change, final assemble went to to balance a dot. Unexpectedly between, two curves are pulled quickly in succession from junction low, back-to-back, the first board piece begin violent campaign to wear, back-to-back the 2nd board piece happen to shake tremendously likewise with displacement, the earthquake happened...

He Manchao introduces, what actually imitate experiment demonstrates is the process of seismic active force, it is the physical experiment of phenomena of pair of change of stress of earthquake of plain of short of Wenshui River. Seismic stress increases, arrive to have a process greatly as a child, two force are centered ceaselessly, the phenomenon that appears suddenly to drop unexpectedly, it is the process that an endless force collects to be released again next. Through imitate the experiment can see, before seismic happening, the athletic curve of fault is active, also be unusual, can be calculated from which and analyse the trend that exert oneself. This that is to say, actually before the earthquake, board piece athletic curve had issued warning signal, if pass the instrument that monitor to take this kind of signal in time, can forecast an earthquake well and truly. This Long Menshan ruptures belt produced earth shake, but very a paragraph long before this period, this area is relatively smooth, but it is actually building up ceaselessly force, final ability is unified release. Actually, if one board piece often a few shake smally, release force ceaselessly, shake of not incidental instead earth. He thinks, a few monitoring and warning device that give through special development can be placed in area of a few fault, the athletic condition of the fault that monitor, if this board piece have the sign that produces earth shake, force accumulation reachs 2 kilometer point of subterranean, the instrument that monitor can be monitored ahead of schedule come out. This is meant, when when the information before shake can be forecasted successfully ahead of schedule, be not far.
