Geotechnical Engineering

The project site is located on the north side of Dalian Bay between Heshang Island and Mianhua Island (in the west) and adjacent to Liaoyu Group in the east. The working section of 0.3 Mt ship repair berth (length 394m) is 335m long, with the top width, top elevation and bottom elevation of 60m, 5.5m and -10.0m respectively, and the width of berthing waters at the apron is 120m.
The level-2 survey site of this Class-II project is a submarine plain, with a level-2 foundation and the Class B geot......

This project mainly involving the underwater bank on the east and west coasts of Dalian Hutan Bay completes the revetment works for coastal environmental governance and modification. The near-shore submarine elevation is 0.11~-11.90m with significant changes of water depths, and the exploration operations are greatly affected by water depths and swells. Considering the complicated formation conditions, the Class of geotechnical survey is classified as Class A.
The reclamation and excavation are......

The project site is located on the north side of Chengzitan-Bachagou Line and adjacent to the southern Culture and Art Square of Changxing Island. With the terrain conditions featured in high west/north and low east/south, the ground elevation of construction site is 26.0~33.5m which means the great topographic relief. This hilly limestone area formed by tectonic denudation has a complex foundation and certain aeolian dunes and exposed bedrocks on the surface layer, equipped with the culverts, w......

It is a large-scale water transport project located in waters outside the east breakwater of Dalian Changxing Island North Port Area. The project construction mainly involves the underwater bank, and the submarine elevations within main structural area of the terminal and the harbor/turning basin are -25.30~-21.60m and -24.50~-18.40m respectively. Exploration operations are greatly affected by water depths, swells and ocean currents, and the Class of geotechnical survey is classified as Class A.......

Located in Liushu Village, Hongqi Sub-district, Ganjingzi District, Dalian Vanke Xizhigu Residential Project has the floor and construction areas of about 300,000 square meters and 400,000 square meters. The length and height of the rock-soil slope involved are about 189m and 7~14m respectively.
The main purpose of project design is to evaluate the slope stability, provide the calculation parameters required for the design of slope supports, and propose the safe/reliable, economical, rational, ......

The project site of Deepwater Engineering Innovation Experimental Base is located on the campus of Dalian University of Technology. The foundation pit covering an excavation area of 5585.1 square meters at the bottom has three parts (third steps). The first layer is equipped with the permanent support of cast-in-place reinforced concrete slabs + tensile prestressed anchors; the second layer inside the foundation pit of first layer has the permanent support of secant piles + pressure prestressed ......
