摘要： 对杠杆式固结仪和全自动气压固结仪在工作原理、操作方法、压力控制、自动化程度等性能方面进行比较，总结了各自的优缺点。通过进一步比较其实际应用，指出了两种固结仪在不同试验项目中各自的无法替代性，以及二者在某些试验项目中的完美结合。结合我国目前固结仪的发展现状，从经济效益、效率及数据可靠性等多方面因素综合考虑，建议配合使用两种固结仪，对现有的固结仪进行改进，使其更完善。

Abstract: Two commercially available consolidometers are introduced in terms of their working principles, operative procedures, compressive pressure control, level of automations as well as advantage and disadvantage of each type of equipment .Throughout commercial laboratory consolidation tests, each type of equipment could not replace the other type. In some projects, the combinations of both types of the consolidometers are satisfactory. It is concluded that, under the state of the practice, the combination of both type of equipment is necessary from the comprehensive considerations of the cost, efficiency as well as the data reliability. The improvement recommendations on the commercial consolidometers are provided.
