Method for building Dongfeng recovery landing test site in different places

The invention discloses a method for building a Dongfeng recovery landing test site in different places. The method comprises the following steps: determining the size of the test site according to the amplitude of vertical vibration waves, the amplitude of horizontal surface waves and the maximum horizontal speed when a reentry capsule lands; determining the proportion of a rock-soil body and broken stones in gravelly soil required by backfilling; digging a pit body according to the determined size of the test field, and laying a polyethylene film on the boundary of the pit body; and uniformly mixing the rock-soil body and the gravel according to the determined ratio to obtain gravel soil, backfilling the gravel soil into the pit body, and enabling the compactness of the test field to reach the standard. The method has process advancement, and a method and thought are provided for construction of a remote spacecraft reentry capsule site. 本发明公开了一种异地建造东风回收着陆试验场的方法，包括：根据竖直振动波振幅、水平表面波振幅和返回舱着陆时的最大水平速度确定试验场的尺寸；确定回
