Wang, Q. and Fu, Q., 2020. Research on mechanical properties of Port Rock under different water conditions. In: Hu, C. and Cai, M. (eds.), Geo-informatics and Oceanography. Journal of Coastal Research, Special Issue No. 105, pp. 223–227. Coconut Creek (Florida), ISSN 0749-0208.

Rocks are widely used in port engineering, in applications such as port revetment and foundations of coastal buildings, so the nature of the type of rock used is important role in determining their safe use. Owing to the long-term effect of water on port rocks, the state of water has a large impact on them. There are cracks and joints in the rock, and water intrusion will soften the mineral composition of the rock, resulting in the decrease of rock strength. Under the action of low temperature in winter, the water in rock cracks freezes and causes frost heaving, which leads to the increase of rock cracks and the decrease of strength after melting. In this article, the port rock mass is taken as the research object, and the orthogonal experiment is carried out for the port rock with different water content, different temperature, and different freezing and thawing times, and the action law of various states of water on it is obtained. The research results have reference value for port engineering.
