1.On the basis of the construction control tests of the expressway subgrade, the contrast tests and correlation analyses between FWD and Benkelman Beam are done through the tests to the different sections and soil quality of the subgrade, and the control index of subgrade tests using FWD are also given.
3.By the analysis of the compact effectiveness on clay and sandy soils, it is proved that impact compaction is good for compacting the subgrade in deep depth and the effect on clay is better than that on sandy soil.
4.To improve the bearing capacity in varying ground conditions, soft spots are usually filled with consolidated hardcore or a weak concrete, before the foundation is laid.
5.The guests were sitting at long trestle tables under a ceiling of vines, or dancing in a clearing of beaten earth.
6.Under four waterpower conditions, the adsorption effect in a recirculating flume is studied. Under the same water depth status, the phosphorus removal effect is the higher with the higher velocity.
9.The Loess Plateau, a dense warren of eroding canyons where some villages are unreachable by roads, is separated from much of the change stirring up China.
10.Mechanical stabilization consists of adding granular or cohesive materials , depending on which is the most suitable , to the subsoil to improve its grading .
