软土地基促渗技术试验研究与分析

我国软土分布广泛,考虑充分发挥软土地区特点,取长补短,开展促渗技术研究.通过室内模型试验,研究了不同砂井半径、砂井深度、砂井水量对浸润水头线的影响,同时基于试验工况,开展了促渗公式模拟与解析研究,结果与试验拟合较好.最后,基于以上分析计算,对实际工程淹没水位进行了演算,配合促渗技术,给出了灌木、乔木等植物的选择建议,可供类似工程参考.

Experimental Study and Analysis on Infiltration Promotion Technology of Soft Soil Foundation

The soft soil is widely distributed in China. So it is considered to give full play to the characteristics of soft soil areas, learn from each other and carry out the research on infiltration promotion technology. Through the laboratory model test, the influences of different radius and depths and water flows of sand well on the infiltration head line are studied. At the same time, based on the test conditions, the simulation and analytical analysis of the infiltration promotion formula are carried out. The results are in good agreement with the test. Finally, based on the above analysis and calculation, the submergence level of actual engineering is calculated. Combined with the infiltration technology, the suggestions on the selection of shrubs, trees and other plants are given, which can provide reference for similar projects.
