In my impression, doctoral dissertations in colleges and universities are relatively thick, generally more than 150 pages, and some even reach more than 300 pages. How many pages should I write for my doctoral thesis to start literature review and reference? I can add dozens of pages. If you use a larger font and larger line spacing, you can also increase the page number. If you don't think this is a good idea, you can also post some stress nephograms, displacement vector diagrams and plastic failure zone distribution maps under different working conditions in the numerical simulation chapter, which can be easily extended to more than 250 pages. But do you think it makes sense? On the other hand, if you find an essential principle governing the stability of rock mass and there is some evidence to support it, writing more than 50 pages is also a high-quality paper! Finally, some netizens commented on my 800-word doctoral thesis and directly advised me to quit my undergraduate course: writing a thesis. Doctor: A book. To tell the truth, the writer is ok. First, it takes a long time to write, and second, it has a sense of accomplishment and satisfaction. People who really admire watching. Reading other people's papers is really tiring. The defense Committee can read several books a day and make suggestions for revision. The master's thesis of our senior and senior has more than 100 pages. When they graduated, they threw away something. The aunt at the door tidied up and said that these children didn't even read the books (papers) they bought, so they threw away the new ones.
