| 7. | Through analyzing the seepage observation data of huangtankou concrete gravity dam , foundation seepage behavior are reasonably evaluated . the reason of seepage force rising of individual monolith is impervious elements " flaw and drain holes " block . 4
分析黄坛口大坝坝基渗流监测资料，正确评价了坝基防渗排水系统的工作状态，指出了个别坝段渗透压力升高是由于坝基防渗帷幕缺陷和排水孔被堵造成，为工程加固提供了科学依据。 |
| 8. | The author has analysed the seepage behavior of the fields in slope with the major parameter of the drain hole diameter and the length of hole . it is concluded that within the usual diameter of the hole , the size of the hole diameter has only minor influence on the field and the length of hole has more distinct influence . the author has analysed the effect of the center spacing change on the seepage field
其次，本文利用排水子结构法模拟排水孔，对排水孔孔径、孔长多种布设方案的渗流场分布对比分析，认为在通常可能取值的孔径范围内，孔径变化对排水孔排水效果有影响，但影响较小；提出了孔径选择的原则；排水孔排水效果对排水孔孔长变化比较敏感，排水孔布设长度的选取应根据边坡处治需要降低水头的沿边坡倾向方向的边坡范围来确定。 |
