Embodiment

[0162] Taking a mountainous area in Southwest China as an example, through relevant data analysis and on-site investigation, the leading factors for the construction safety of highway cutting high slope engineering are geotechnical engineering geological conditions and topographic and geomorphic conditions, and the main stimulating factors are meteorological and hydrological conditions and human engineering activities. Others are subordinate geological environmental factors. The evaluation method and evaluation process are as follows: the overall risk assessment level of a certain landslide is level IV extremely high risk, mainly because the landslide is close to the Yangtze River and the local river, it is an ancient landslide along the waters, and there are tunnels passing through the landslide body, so the overall risk level of construction Higher, the evaluation results are shown in Table 4:

[0163] Table 4 The overall risk assessment results of a landslide construction s...

Abstract

The invention provides a side slope construction assessment method based on a centesimal system and a multistage index system. The method comprises the following steps of taking a full-line high cutting side slope project of a construction project as an assessment object, carrying out total risk assessment on full-line high cutting side slope construction safety and determining a risk grade; dividing a high side slope construction project into several special projects, taking the divided special projects as the assessment objects and carrying out special project risk assessment; analyzing a special project risk assessment report to acquire a major risk source influencing a safety risk; and for the major risk source, making risk control measures of the major risk source. The method has advantages that according to complex and various kinds of express-way high cut side slope geology conditions, a changeful construction environment, a project characteristic of a large difference and the like, the side slope construction assessment method is provided; the risk of the side slope construction can be accurately assessed so that the construction can be guided; side slope construction safety is guaranteed and side slope construction generation accidents are reduced.

Description

technical field [0001] The invention belongs to the technical field of road engineering construction, and in particular relates to a slope construction evaluation method based on a percentage system and a multi-level index system. Background technique [0002] With the rapid development of my country's economy, road network construction has entered a high-speed development period, especially when expressways gradually enter mountainous areas, which has become an important part of current road network construction. With the continuous expansion of highway mileage, the complexity of engineering construction is also increasing, and construction safety is facing a severe situation. [0003] High slopes are high-risk links in highway construction, and production safety accidents occur frequently. It is of great significance to carry out risk management and control on high slopes. At present, there is no effective method for efficient assessment of high slope construction risks. ...
