I. About Us
The Department of Road & Bridge Engineering at Huazhong University of Science & Technology (HUST) was founded in 2000. Before then, it was part of the Department of Urban Construction in the former Wuhan Urban Construction College, one of the three universities/colleges merged to form the new HUST. Professor Guoding Wang, a renowned bridge expert, was the first head of the department. Currently, both Master’s and Doctoral Degrees are awarded in three areas: bridge & tunnel engineering, road & railway engineering, and geotechnical & underground structural engineering. There are three teaching and research sections in the department, i.e., road, bridge and geotechnical engineering teaching and research sections.
There are currently more than 30 faculty and staff members in the department, including 13 professors, 11 associate professors and more than 5 lecturers. Among them, 25 possess Doctoral Degrees.

III. Introduction of laboratories
Geotechnical Engineering Laboratory:
The geotechnical engineering laboratory has the following devices:
1. Large-scale direct shear test system
The laboratory has a Cyclic ShearTrac System, which is a universal, large-scale shear system capable of performing the consolidation, cyclic shear, and static shear phases of a direct simple shear test under full automatic control. It can also perform large direct shear for studying the interface behavior of geotextile or soil-structure interface. The system consists of a computer controlled unit that utilizes micro-stepper motors to apply the vertical and both static and cyclic horizontal loads to the soil specimen.
2. Cyclic triaxial test system
The laboratory has a dynamic triaxial testing device, which can be utilized to determine the shear modulus (G) and damping ratio (D) of soils in either undisturbed or reconstituted states by using either load or displacement controlled cyclic triaxial system. The cyclic triaxial test is applicable to both fine grained and coarse grained soils. It is also used to study the liquefaction characteristics of silty and sandy soils.
3. Temperature controlled creep test system
The laboratory has a creep test machine which is a temperature controlled, creep test system capable of performing tensile and compression creep test under full automatic control. It contains three test devices for three independent tests. The system consists of a computer controlled unit that utilizes micro-stepper motors to apply the vertical loads. The uninterruptible power system can support the whole system continuous work for more than 3000 hours.
4. Conventional triaxial test devices
The laboratory consists of four triaxial testing systems which can be used for conventional triaxial tests (CU, CD, UU) as well as isotropic / anisotropic consolidation tests. Each triaxial testing system includes a closed-loop controlled load frame, automatic strain controlling unit, volume measuring/controlling unit, data acquisition system, transducers and different software solutions.
5. Conventional oedometer test devices
The laboratory has a number of oedometer testing equipments. Each of them consists of a set of consolidation device (including ring, porous stones, water reservoir, and load plate), Dial gauge (0.0001 inch = 1.0 on dial), sample trimming device, glass plate, metal straight edge, clock, moisture can, and filter paper. The standard oedometer consolidation test for saturated clays is the main feature of this experiment. The test is carried out by applying a sequence of vertical loads to a laterally confined specimen. The vertical compression under each load is observed over a period of time, usually up to 24 hours. Since no lateral deformation is allowed it is a one-dimensional test, from which the one-dimensional consolidation parameters are derived.
Bridge Engineering laboratory:
The bridge engineering laboratory has the following devices:
1. Large span bridge static and dynamic tests
The laboratory has suspension and cable-stayed bridge models. All of cables are mounted with tension transducers. To change situation of cables and install different sensors, static & dynamic tests can be conducted in this lab.
