Relationship between drainage capacity and foundation settlement at Pre Rup Temple: Basic study on Khmer architecture drainage systems Part 1

Abstract

Abstract In the ancient city of Angkor, heavy rainfall was common in the rainy season and rapid rainwater drainage was important for maintaining urban functions. This study focuses on the drainage system of an example of Khmer architecture from the Angkor period, the Pre Rup temple built in the year 961. We analyze the relationship between the drainage capacity and foundation settlement, revealing that the foundation settlement was larger near drainage channels with a low drainage capacity. After showing that only a few of the drainage channels function properly, it is possible to have some certainty on the relationship between the drainage capacity and foundation settlement.
