目前,筒仓仓壁所受的压力,一般采用测试方法(包括现场实测和室内模型试验)和理论计算方法确定.但是,这两种方法都有其缺陷,前者往往由于放置的传感元件精度不高,使测出的压力值失真,而且很难捕捉到瞬间的临界荷载;后者所用的理论公式没有考虑许多重要的影响因素,如颗粒密度、级配和装料方式等,用其计算筒仓所受的动压未免有大的出入.另外,学术界对于筒仓在装卸料时的压力变化的认识尚未统一.有的学者认为筒仓仓壁的裂缝都是在装料时 At present, the pressure on the silo wall is generally determined by test methods (including on-site measurement and indoor model test) and theoretical calculation methods. However, these two methods have their drawbacks, the former often due to the placement of the sensor element accuracy If it is not high, the measured pressure value is distorted, and it is difficult to capture the momentary critical load; the latter theoretical formula does not consider many important influencing factors, such as particle density, grading, and loading methods, etc. The dynamic pressure on the warehouse is inevitably large. In addition, the understanding of the academic community on the pressure changes during loading and unloading silos has not been unified. Some scholars believe that the silo wall cracks are loaded
