Good you have attempted book chapter

usually on a particular theme book containing several chapters is written and published.

there should be a common subject matter like ADVANCES IN GEO-TECHNICAL ENGINEERING under which yours will fit as a chapter

and collection of other chapters from various authors together it becomes Book

for which you have search for a publisher like Esevier, Springer, Science Domain etc

they will evaluate your idea and chapter and other chapters and contributors and their credentials 

one of the leading author will take responsibility as a Editor and all the responsibility of correspondence and subject matter is with him/her

Contact your own senior professors form your dept.
