Abstract:
Objective:To optimize the decompression scheme of conventional air diving based on the data of 5 factors.Methods:Five factors, i. e. bottom material, water temperature, water current velocity, individual susceptibility to decompression sickness, and labor intensity, associated with decompression safety were calculated and analyzed, to select the most optimized decompression scheme.Results:A modified formula for the duration of underwater operation was proposed, and it was proved safe and reliable during the underwater construction of railway bridge pier.Conclusion:Based on synthetical consideration of various factors, i. e. bottom material, water temperature, water current velocity, individual susceptibility to decompression sickness, and labor intensity, an optimized decompression scheme was gained for balancing the decompression efficiency and the safety of divers by modifying the time duration of underwater operation.
