The invention belongs to the technical field of helicopter test flight test, and particularly relates to a civil helicopter ground combined test bench which at least comprises a testing machine, a bench, a testing system, an emergency parking system and a safety monitoring system. The testing machine and the rack are connected through bolts at a mooring point of a frame 1 at the front part of the testing machine, outer flanges at the upper parts of a frame 4, a frame 5 and a frame 6, a newly-added joint at the tail part, an on-board connecting joint of a nose landing gear and a mounting beam of a main landing gear; the test system carries out acquisition, on-line and post-analysis, real-time display and monitoring, alarm and data storage on test signals. The emergency parking system is used for realizing emergency parking in the test process; the safety monitoring system records a test site in real time and monitors the testing machine and the rack in real time at the same time. By adopting the test bench provided by the invention, the working capability, the coordination capability and the matching performance of the transmission part and each system of the helicopter are effectively examined.
