Treatment Technology Of Saline Subgrade On The Yellow River

There exists large area of saline soil widely in China, which contains high percent salt and features salt expansion, collapsibility and corruption and so on. saline soil subgrade in huangfan area is one of the limitations to the development of road construction. Aimed at solving the usage of saline soil subgrade in Huangfan Area, this lecture analyze the way to deal with saline soil subgrade after doing lots of experiments and combining practical experience and then put forward the requirements concerning it.This lecture introduces the distributional rule and types of saline soil in Weifang, and also deals with the results of the present research about it. The character of saline soil program and its shaping theory as well as its negative effect are also recovered.Based on the construction of a road in Binhai Developing zone, this lecture states at length the main technical measures taken during the course of the it. Through analyzing the results of the experiments, we learned about the distributional and moving rules of the salt in subgrade under different conditions and techniques. We also research into the negative effects of different patterns on the roads and according to the present principles of saline soil roads, we put forward a few effective techniques to deal the saline soil subgrade in Huangfan Area.
