Do you have backup??If you don't have backup then there is only one way to resolve log file corruption that is to rebuild log file. Check this article, it will help you to handle log file corruption: http://www.recoverdatabase.blogspot.com/2012/07/how-to-deal-with-log-file-corruption.html
You should delete that blog post. That is very, very bad advice. You should NEVER detach a corrupted database. It is very likely that the database won't be able to shut down cleanly and then the database won't be able to be reattached and now instead of having just a corrupted log file, you will have lost the entire database.
