                江苏省科学宫A挡墙土层锚杆支护工程

                江苏省科学宫A挡墙土层锚杆支护工程




                      该边坡位于定淮门石头城路118号,西临※秦淮河,东靠电视塔,在古林公园的西侧山坡处。因工』程建设需要,需对邻近山体进行切ω 坡造地,建设坡顶观光◆广场及坡脚停车场,切坡段长54.00m,坡高19.50m,坡度系数1:0.25,边坡采用永久性◎土层锚杆挡墙进行支护。该工程于1999年9月5日开工,至2000年1月1日结束,总计完成土锚364根;树根桩20根;人工挖孔桩21根;挂网喷浆面积1381m3;浇筑砼挡◤墙1129.8m2
                      本工程为永久性边坡,不仅←坡度高,且施工难度大。A挡墙在施工前【,又无工程地质勘↓察,后经补勘发现,该场地工程地质条件十分复杂,南段15.0m为原坍方段,坍方■深度超过15.0m,纵向宽度大于6.0m,坍方ㄨ段为回填的素填土,土质松散。中部长约20.0m为深大凹♂沟,深14.0m,纵向宽10.0m,凹沟中为软塑的粉质粘土,工程地质条件ぷ很差,且风化基岩面〗有较多的地下水,软弱土层达14.0m以上,结构松散,内聚力低,土层@ 不能自立,并富含地下水,这对高边坡挡墙的稳定□十分不利,若采用原B段挡墙设计方〇案施工,难』以保证坡体的稳定,故本工程采用动※态设计,跟踪质量监控的施工原则▲,对原设计进行了局部调『整,从而满足了工程的要求。
