| 3. | The results show that the ultimate bearing capacity can be increased 10 % - 40 % and the lateral displacement and vertical settlement can be decreased 20 % - 50 % and 30 % - 50 % respectively , if the sand foundation is reinforced by geogrid
由模型试验测量结果得知，在砂土地基中铺设塑料土工格栅，可以使承载力提高10 % ~ 40 % 、侧向位移量减少20 % ~ 50 % 、地基轴线处竖向沉降减少30 % ~ 50 % 。 |
| 4. | Based on four project cases of vibro casing cast - in - place pile in silty sand foundation , the liquefaction of sand and its consequent pile breaking are analyzed , and suggestions on how to adopt values of the design parameters of a single pile are presented
摘要以4个在粉砂地基中均采用振动沉管灌注桩的工程为例，分析了施工中砂土的液化及由此引起的断桩，并对单桩设计参数的取值提出了建议。 |
| 5. | It is also the key factor to improve the highway grade in these areas . the sand harm usually happens and the roadbed is obviously influenced by the sand foundation stability condition and the groundwater if the roadbed earthfill height is low . on the contrary , the wind erosion usually happens if the height is high
公路路基的合理高度是保证沙漠公路不产生沙害的主要因素之一，同时是提高沙漠地区公路等级的关键，沙漠公路路基填土高度低，则易出现沙埋病害，路基受沙漠地基稳定状况及地下水的影响显著，反之，则易出现风蚀病害，并存在高填方路基和稳定性问题，工程造价相应增加。 |
| 6. | The papers and technical reports about the oil tank foundation treatment shows that in our country abundant experiences have been built up in dealing with the soft clay foundation , while there were few cases for sand foundation . analyzing the geological condition , the author proposed that the foundation soils at shuguang pump station belong to high - permeability sand layers
根据曙光泵站地区的地质条件，论文认为该区主要是一套以高透水性的砂类土为主的地层，粘性土层较薄且富夹薄层粉细砂，地基土的水平向与垂直向排水条件良好。 |
