航天返回舱着陆冲击模拟试验床建造过程控制研究
摘要:应用岩土工程基本方法和手段,按照载人航天返回舱计划着陆地的土质条件,建造了返回舱着陆冲击试验模拟试验床,建造过程严格控制材料质量、施工技术参数和施工方法,采用轻型动力触探试验、测试土层含水量和干密度、小直径载荷板试验等主要现场测试方法,及时评价试验床的质量状况,实现了信息化控制施工,保证了模拟试验床的建造质量,对我国国防科技领域的试验研究具有重要意义。
Abstract:Based on the earth quality condition and basic method of geotechnical engineering, an impact imitating test bed of the spaceflight reture capsule is built. The material quality, parameter of construction technology and construction method is strict controlled in this building process which adopts field test data such as light dynamic penetration test, water content and dry density and little diameter load board experiment. According to thee methods, it can appraise the quality situation of testing bed in time, and realize informative control construction. Then the build quality of the bed is guaranteed. This research has an important meaning in science and technology field of our country national defenee.
