| 中文摘要:“涌沙”是陕北沙漠区坑井工程普遍遇到的地质灾害问题，不同工程位置、不同岩土结构特征、不同水文地质条件下，井内涌沙的潜在危害迥异。研究竖井所在位置的地质条件，针对性地采取措施，避免竖井内涌沙是工程顺利竣工的关键。通过对已有工程事故的分析汇总，归纳出沙漠区可行的3种交通竖井方案及其适用的地质条件，并指出了每种方案在设计及施工过程中应引起高度重视的节点问题，具有一定的推广价值，可供同行借鉴。 |

| Abstract: ‘Quick inflow of sand’ is a common geological hazard in the shaft works in desert area in northern Shaanxi. It has different potential hazard according to the project position, structural features of rock or soil and geo-hydrological conditions. The project can be successfully accomplished only by proper measures according to the geological conditions of shaft to avoid quick inflow of sand. The combined analysis was made on the experienced accidents, 3 kinds of feasible access shaft scheme and adaptable geological conditions were inducted with the important attentions in each design and construction process. |
