| 2. | Application of through - water lining in canal rebuilding works in high underground water level 透水衬砌在高地下水位渠道改建中的应用 |
| 3. | The application of mildtype well point precipitation decrease underground water level method in project 轻型井点降水法在工程中的应用 |
| 4. | It was remarkable that epidemic of wheat scab was affected by both the climatic factor and the underground water level and displayed complex geographic patterns 流行分区受气候和地下水因素制约,呈现比较复杂的地理格局。 |
| 5. | Along with the developments of skyscraper , subwsty , long tunnel , etc . the problem that lower the underground water level is increasingly outstanding 随着高层建筑、地铁、长大隧道等工程的发展,降低地下水位的问题日益突出。 |
| 6. | The grade distribution graph shows that the land quality is related to the soil quality , soil obstacle layer , irrigation , the underground water level and other indicators 这说明了土地质量与土壤质地、障碍层次、排灌保证率、地下水位、道路通达度等指标密切相关。 |
| 7. | The epidemic zones were differentiated at the township level based on the correlation between the scab severity and underground water level according to regression analysis 在气候分区的基础上,根据地下水位与发病率的回归关系,进一步以乡镇为单位划分小麦赤霉病流行区。 |
| 8. | Because of regional underground water level continual dropping and climate changing to aridity , land desertifacation and degeneration of glassland and tundra will tend to worse in short period 由于区域地下水位的持续下降和气候向干旱化发展,土地沙化、草场退化及多年冻土退化短期内将趋于恶化。 |
| 9. | The sliding resistance mechanism of deformable earth bodies by means of well point drainage lies in lowering the underground water level to reduce the water content of the earth bodies and raise the shear strength , improve the stability of the deformable earth bodies and increase their sliding resistance 摘要井点降水常用于地下水位高出开挖建基面许多或含水丰富的土体基坑工程中,井点降水在土质变形体中的抗滑作用机理在于,通过井点降水,降低地下水位,使土体的含水量减少,提高其抗剪强度及变形体的稳定性,增加其抗滑力。 |
| 10. | In development of deep foundation engineering , it is necessary introduce information construction method into the deep foundation engineering , for reducing the pit trouble . the information construction method is a kind of moderon construcion management way to make use of system engineering , includes the informationg acquisition back coupling , back analysis , control and decision . the research is for example runyang changjiang river highway bridege , expounds the method how to apply the information construction method into the practice engineering , at the same time , discussing some the factor of influcing the deep foundation stability how to influce the deep foundation ' s stability . form the research , we have some following results : 1 . in construction process of super and deep pit , super pore water pressure creation has related to outside load , soil layer conditions , and underground water level 在深基坑工程建设迅速发展的同时,为了减少基坑事故的发生,需要将信息化施工这一理念引进到基坑工程的施工过程中,信息化施工是运用系统工程施工的一种现代化施工管理办法,包括信息采集(监测) 、反馈、反分析(预测) 、控制与决策等几方面的内容,本文以在建的润扬长江大桥北锚锭深基坑工程为例,系统的阐述了这一施工理念在实际工程的具体应用过程,并通过这一应用过程探讨影响基坑工程安全稳定的相关因素对基坑的影响程度。 |
