This is the most frequently faced issue for almost all the DBAs where the logs grows and fills out the disk.

•What are some reasons the transaction log grows so large?

1. Long Active Transaction
2. High logging transactions like Index rebuild, re-organise, Bulk Insert, Deletes etc.
3. Any HA like Replication, Mirroring configured which holds the log and does not allow it release the log space

•Why is my log file so big?

Check for the log_reuse_wait_desc column in sys.databases table to know what is holding the logs from truncating:

select name, log_reuse_wait_desc from sys.databases 

•What are some ways to prevent this problem from occurring?

Log backups will help you control the log growth unless there is something that is holding up the logs from being reused.

•What do I do when I get myself on track with the underlying cause and want to put my transaction log file to a healthy size?

If you have identified what actually is causing it then try to fix it accordingly as explained in below page.

Having proper log backups scheduled is the best way of dealing with log growth unless for an unusual situation.
