On the basis of stability analysis, the author takes the k27 + 825 slope from the type of slope which has lest stability as an example . according to its basic feature, the design ueses the choosed best reinforce and control scheme : lattice beam, anchor wire, grouting and abstraction of water . in the course of design, the author takes into account not only reasonable optimize of whole control plan but also local measure such as whether the unstable block will shear from vnlnerable sections when control plan is laid out concretely, in order to reach the goal of reasonable design and effective control 在穩(wěn)定性分析的基礎(chǔ)上,以邊坡穩(wěn)定性最差的一類(lèi)中的k27+825邊坡為例,結(jié)合其自身的特點(diǎn),用優(yōu)選出的加固防治方案:框架梁+錨索斗灌漿+排水進(jìn)行設(shè)計(jì),設(shè)計(jì)中既考慮總體防治方案的合理優(yōu)化,又充分考慮了加固工程的具體布置時(shí)是否存在不穩(wěn)定體從錨索或框架梁的薄弱部位剪出的可能性等一些細(xì)部措施,以達(dá)到合理設(shè)計(jì),有效及經(jīng)濟(jì)治理的目的。
