Some innovative results are listed below:1、According to the lithologic characters,lithofacies,genetic classification and the geomorphy,the Quaternary system is divided into piedmont-gully\'s and plain\'s. The piedmont-gully\'s Quaternary sediment,which is about 3~20 meters in thick,is in the western hills of the study area.The plain\'s Quaternary sediment is widely distributed in the study area,which is about 30~60meters thick and become thicker from southwest to northeast.2、The Quaternary sediments of plain can be divided into five sedimentary cycles.The Late Pleistocene series Quantan group,at the bottom of the Quaternary System,is constituted by a fluvial facies-river and lake facies sedimentary cycle. The Late Pleistocene series Jiashan group,at the middle of the Quaternary sediment, is constituted by two fluvial facies-neritic facies-river and lake facies sedimentary cycles.The Holocene series Binhai group,at the upper of the Quaternary sediment, is divided into three parts,the under layer and middle layer are constituted by two littoral facies-river and lake facies sedimentary cycles,the upper layer is constituted by paludal facies,which was deposited at the lower-lying land like West Lake, Jiangcun-Gu dang,Xianghu lake,and coastal-estuary facies in other area.3、Folding and fault activities were weak in Quaternary and the tectonic activity had little influence on the Quaternary sedimentation.The ancient landforms,the evolvement of the river system and transgression were the main elements which controlled the Quaternary sedimentation in Hangzhou.The ancient landforms formed the basis of the Quaternary sedimentation.The evolvement of the river system and transgression individually or jointly controlled the Quaternary sedimentation of this area.4、The alternation of the climate was the main reason for the evolvement of the river systems and transgression,and it\'s also the reason why the Quaternary system of Hangzhou has the special sedimentary structure which is called soft interbed with hard layers.
通过研究取得了以下成果:1、根据岩性、岩相、成因类型和地貌特点,将本区第四系划分为山麓沟谷区沉积和平原区沉积:山麓沟谷区第四系主要分布于西部丘陵地区,厚度较薄且变幅大,一般厚3~20m;平原区第四系广布分区,由南西向北东逐渐增厚,一般厚30~60m.2、平原区第四系自下而上大体由五个完整或不完整的沉积旋回构成:底部上更新统全塘组,由河流相—河湖相的沉积旋回构成;中部上更新统嘉善组,由河流相—浅海相—河湖相两个沉积旋回构成;上部全新统滨海组,其下中两段由滨海海湾相—河湖相的两个沉积旋回构成,上段由西湖、蒋村—古荡、湘湖等低洼处沉积的湖沼相和其他地区沉积的滨海河口相构成。3、第四纪以来,研究区内褶皱、断裂活动微弱,构造运动对第四系沉积的影响不大,古地形、古水系的发育、变迁和海侵是杭州市第四系沉积的主要控制因素:古地形构成了第四系沉积的基底,水系与海侵在其后的不同阶段或分别或联合的主导了区内的第四系沉积。4、水系的发育、变迁和海侵的共同原因是天气变化,正是由于第四纪以来"冷热交替"的天气特点形成了杭州市第四系"软硬互层"的特殊沉积结构。

The presterssed anchor cable frame combined with backwall, drainage is necessary due to longtime sability and permanent utilization.Firstly,according the study of engineering of geology situation of the high slope, the mechanism of deformation failure and the major hazard of the high slope of PanMei is analysed comprehensively.And the whole slope is divided into two different geology enginnering areas:Western slope(1160 section plane -1240 section plane)and Eastern slope(1240 section plane -1320 section plane). The result of 3D numerical simulation is the same as geology judgement. Later,slope cut (1:0.75) is implemented based on the engineering comparison and criterion.Meanwhile, Limit equilibrium method , Monte Carlo Probabilistic slope stability the stability , Sensitivity analysis and Finent element method of for assessing the cutted slope stability is carried out. The result indicates that Western slope is instable, Eastern slope is relatively stable.So much attention should be paid to Western slope.Different reinforcement measures in different areas are given according to its stability and meet economical request. Gravity wall is introduced in accordance with landform in order to prevent small falling at the foot of the high slope ,which will be a threat to the high slope stability. Handling measure is also applied to Eastern slope. At last,FLAC3D numerical analysis shows the feasibility and reasonableness of the handling measure of the high slope.
论文首先研究了边坡的工程地质条件,全面分析边坡的变形破坏机制和边坡的主要地质灾害,将边坡分为西段不稳定边坡区(1160剖面~1240剖面)和东段相对稳定边坡区(1240剖面~1320剖面),通过三维数值模拟再现了边坡在自重作用下的破坏机制和过程;在此基础上通过工程类比和规范要求,确定按照1:0.75进行放坡处理,并分析了放坡后边坡的稳定性状况,分别通过极限平衡法、蒙特卡洛法概率分析、参数敏感性分析和有限元稳定性计算等多种方法对边坡在各种工况下的进行稳定性研究,计算结果表明,西段边坡较之东段边坡稳定情况差,是边坡支护的关键之处,而东段边坡相对是稳定的;边坡的综合治理措施选用的是框架锚索并结合挡土墙和排水工程,治理设计根据不同区段的稳定性情况采用不同的支护结构,做到了经济合理的要求;在边坡的坡脚设置重力式挡土墙,防治边坡小规模的崩塌,会对上部的锚索支护护造成不利影响,进而影响边坡的稳定;东段边坡的填方区也给出了治理对策;最后通过三维显示拉各朗日有限差分程序(FLAC3D)模拟了高边坡放坡和支护效果,论证了治理措施的有效性和合理性。
