embankment foundation
2.A model test in an organic glass flume with a scale of 1:100 was performed to demonstrate the generation and evolution of piping in embankment foundation with different depths of cut-off wall.
4.The research result is of certain reference value for engineering of reinforced embankment with soft foundation.
5.Abstract: Taking “The Great Embankment Around The Tai Lake Project” as an example,in which we have repaired a small part of collapsed embankment successfully.some valuable methods and steps of mending collapsed embankment on mollisol foundation are studied in the paper.
6.Product function :soft soil subgrade strengthening , reinforced embankment &slope, strengthening separation, bounding deformation of foundation, prevent road from reflection crack, increasing the intensity of subgrade .It can strengthen soft subgrade of kinds of roads and railways; prevent road from reflection crack; enhance the strength of subgrade ;reinforcedriverbank , embankment and slope; homogenize the stress; adjust settlement; improve the stability and bearing capacity of the basement; strengthen road and bridge tops.
7.The research results provides important basis for the design of side slope of swelling clay embankment dam and the consolidation and treatment of swelling clay foundation.
8.NUMERICAL SIMULATION OF DISPLACEMENT FIELD FOR RIGID PILES WITH CAP COMPOSITE FOUNDATION UNDER THE EMBANKMENT
9.Abstract: A brief introduction is given to the treatment of the Zeya dam foundation,principles of seepage control and design of the concrete face rockfill dam of the Zeya reservoir.As for the excavation of the sand-gravel zones,except the toe slab and its 1/9 bottom width down stream,the alluvial layers are excavated to the micro-weathered rocks,while the other sections remain unexcavated.Regarding to the treatment of the fracture zones,concrete filling is used for the toe slabs and semi-permeable materials are used for other section.According to the construction characteristics,a filter is placed in the down stream embankment foot.To improve the integrity of the dam foundation and anti-seepage capability consolidation grouting and curtain grouting are adopted.As a result safety,economic benefit,convenience in construction and good performace are achieved.
