Stability And Anti-Slide Pile At Slope Landslide In Study On The Effect Of Governance

Infrastructure construction in the process of China's economic soft landing is of crucial importance.It not only can obviously boost economic development but also consume excess capacity.Therefore,during the 13 th FYP period,the state continuously improves and encrypts the road network while the western region will be Our vanguard of highway construction.Although the policies of the western region are gratifying,the road construction in the western region has been affected by the terrain.In particular,the selection of routes often occurs in the mountains under the limited topography.There are many mountains in the west,peaks and valleys,varied climate,coupled with the high ground,causing serious rock weathering phenomenon.Due to the complex terrain in the mountainous area,poor geological conditions and narrow plane stretches,it is unavoidable that a high slope may occur during the construction of the infrastructure.However,due to the complicated geological conditions,the service level of high-grade highways can not be greatly reduced,so the problem of high slopes must be solved.The high slope is an engineering geological body formed by human activities or natural environment.It is in the form of a slope with a large slope.Projects such as the construction of expressways in western mountainous regions inevitably encounter high slopes.High slopes mean dangerous sources.Therefore,during construction,we will conduct a series of studies on the high slopes and pay close attention to these high slopes May cause harm and loss.Chongqing S309 Daiei Road is the main road connecting Dazu and Rongchang,and is responsible for the tourism and transportation tasks from Rongchang to Dazu and Baoding.During the construction of Da-Rong Road,due to the abundant rainfall in summer,many landslides occurred.Among them,the landslide area of K66 + 100 is about 37,000 square meters.In order to ensure the stability and safety of slope engineering,this paper studies the reasons of landslide and the anti-slide pile-based measures based on the cutting slope.In this paper,the engineering geological features and hydrogeological conditions are analyzed.The shape,structural characteristics and geotechnical properties of the slope are obtained by drilling,testing,observing and combining engineering experience.The formation conditions,induced factors and mechanisms of the landslide are analyzed.Landslide is the last landslide under the influence of the excavation of limestone surface subgrade on the sedimentary landslide.The landslide is caused by the gravity.Then,by analyzing the stability of the slope with the unbalanced thrust coefficient transfer method,the designed residual sliding force of the slope is obtained.Then after comparison,chose to anti-slide pile-based management measures.Finally,the construction requirements of anti-sliding pile put forward the relevant requirements.After piling,anti-sliding piles are also tested for quality according to relevant specifications to ensure the reliability of the project.
