在杭州城垣西南,钱塘江成反“之”字形曲折绕流而过。本文所涉地段,即傍依曲流凹岸的北坡,东起六和塔、西迄梵村,成一狭长的东北——西南向伸展地带。此处现代自然地质现象的崩塌和滑坡遍处都是,成为本地段斜坡现代剥蚀作用的主导因素。现代斜坡块体运动的结果,不仅使斜坡变形趋向复杂,且给工程上带来了威胁和损失。如在六和塔小学东侧溪谷的西南斜坡上一滑坡,1954年夏,雨后发生滑动,当即摧毁坡脚房屋两间。同年,在省党校新大操场的北侧一滑坡,摧毁阶地面上一些房子后,现已威
In the city wall southwest of Hangzhou, Qiantang River into the opposite “of” zigzag flow around the stream. The site involved in this article is located along the northern slope of the Curved Gully. From the east to the Sixth Pagoda and from the west to the Vatican Village, it forms a narrow northeast-southwest extension. Here, the collapse and landslide of modern natural geology are everywhere and become the dominant factor in the modern denudation of the local slope. As a result of the movement of modern slope blocks, not only the trend of slope deformation tends to be complicated, but also brings threats and losses to the project. For example, a landslide on the southwestern slope of the valley east of Liuhe Pagoda Elementary School slipped in the summer of 1954 and immediately destroyed two houses on the slope. In the same year, after a landslide on the north side of the new large playground at the provincial party school and the destruction of some houses on the ground floor,
