Abstract: The interface of ABAQUS software is complicated,and it takes much time to process data before and afterwards.In light of these problems,C# is used for secondary development of ABAQUS,breaking out from the limit of the conventional development where simple combination of Python script and GUI plug-in tool kit built in ABAQUS is used.When C# is used for programming,the ABAQUS solver is directly retrieved,calculating and reading the results without opening the software interface and displaying the strength reduction factor on WinForm window program.The developed system greatly simplifies the complicated operation to solve specific rock slope engineering in ABAQUS,and lowers the difficulty to operate the software.
