湿陷性黄土地区城市绿化与地基变形的关系研究

湿陷性黄土地区绿化带需灌溉,如果灌溉水量过大将会导致湿陷性土层的含水量增大,当含水量增大至湿陷起始含水量时,湿陷性土层开始产生湿陷现象。为了防止湿陷性黄土地区因大量灌溉水进入土中,导致湿陷,本文根据湿陷性土层的湿陷机理及湿陷性黄土的本构关系,提出湿陷性土层上绿化区域防止湿陷的具体方法。

Research of Making Green by Planting Trees in City and Foundation Subside to the Wet Pitfall Loess

Green by planting trees need irrigate,if irrigating overwater in wet pitfall loess district,lead to the water content of wet pitfall soil layer to enlarge.When the water content enlarging to origin of wet pitfall the water content,the wet pitfall soil layer begins giving rise to the wet pitfall appearance.In order to prevent the wet pitfall loess district from irrigating that the overwater enters in the soil,and leading to the wet pitfall,this text originally constructs the relation according to the wet pitfall loess wet pitfall mechanism of layer with wet pitfall loess,and puts forward making green by planting trees the concrete method that the region prevented the wet pitfall on the wet pitfall soil layer.
