From numerical analysis result obtained by abovementioned two methods (safety coefficient being less than 1.1) and combination with the geological evaluation in situ, the high rock slope of the left abutment downstream is considered as a potentially unstable one under natural condition and pondage cases. So it is necessary to be further studied.

Together with some basic knowledge of Linear Algebra, we prove that there exists a polynomial time algorithm for finding the shortest contractible cycle in an locally LEW-embedded graph. 3. By some results of Minor Theorem, we prove the crossing numbers of some circular graphs C(10,4), C(9,3), C(8,3) on the projective plane.

As the quarry operation evolve, the deeper the pit, the higher and steeper of the highwall, and thus, the influence of blasting vibration may affect the potentially unstable slope which may cause safety problem and result in the shut-down of the overall mining operation.

在露天矿场开采过程中，随著开采深度的增大，其边坡越来越高，特别是对於那些存在不稳定因素的高陡边坡，倘若受爆破震动的影响，极有可能造成边坡的失稳破坏，危及安全生产甚至影响矿山的正常生产秩序。

If seams are not fell flat, you must ensure seams are serged to cover the raw edges and thus prevent raveling.

Thirdly,we study certain Riemann boundary value problems and Singularintegral equations with values in a universal Clifford algebra 〓,by com-bining the classical methods of solving Riemann boundary value problems andsingular integral equations with the Taylor's expansion of regular function in Clif-ford analysis,proving a lemma which is similar to the Painleve theorem in theclassical complex analysis,and the Plemelj formula in Clifford analysis,we obtainthe better results under weaker condition than before.

第三，本文第一次借助于用来解决经典的Riemann边值问题与奇异积分方程的方法来研究Clifford分析中的某些Riemann边值问题与奇异积分方程，获得了在比以前文献中条件更弱的情况下，结论更广的结果，并且，它为更进一步地解决在Clifford分析中一般的Riemann边值问题与奇异积分方程提供了基本的解决思想，为这一新的研究领域奠定了基础。

For the slope protection,domestic and foreign have various methods,such as:clean surface, and shotcrete stone surface and the use of concrete,asphalt,riprap,etc.,but these have a fatal weakness,the use of clean face,and shotcrete stone surface and the use of concrete,asphalt,riprap protection methods such as the slope,often due to excessive destruction of the human impact of the original natural and ecological environment.so that the entire road is almost formed a gray line,and While these protective measures outside the slope formed a protective layer of solid layer,but if there is a protective layer of water into the lower water flow and form,these protective measures will also be destroyed.

对于边坡的防护，国内、国外均有多种方法，比如：抹面、喷浆、石砌护面以及利用混凝土、沥青、抛石等等，但这些都有着致命的弱点，利用抹面、喷浆、石砌护面以及利用混凝土、沥青、抛石等方法进行防护的边坡，往往由于过多的人为影响破坏了原来的自然生态环境，使整条公路几乎形成一条灰色的路线，同时，这些防护措施虽然在边坡外面形成了一层坚固的防护层，但只要有水渗入防护层下部并形成水流时，这些防护措施也将被冲毁。

The disaster of rockfall has became one of research subject which is second only to slope stability, particularly in engineering of high and steep rock slope.

在边坡尤其是高陡岩质边坡工程中，崩塌落石灾害已经成为仅次于边坡稳定的研究课题之一。
