Combined with the Wuyuanwan Tunnel Project of Xiamen Rail Transit Line 2,there is residual sandy clay,fully and strongly weathered granite layers underneath,and there is special rock and soil developed such as liquefiable sand,soft soil,residual soil and fully weathered rock.In the geological section of complex sea area with poor soil uniformity,comprehensive technologies such as marine surveying and mapping,reasonable arrangement of exploration holes,geophysical exploration,field test,indoor test and theoretical calculation used to study the engineering geological and hydrogeological conditions,evaluate the stability and suitability of the site,and put forward targeted engineering prevention measures,so as to provide basis for design and construction.
