Problems solved by technology
[0003] The technical problem to be solved by the present invention is that in the prior art, there is a lack of guiding methods for the design and construction of the relevant technical design and construction of the bridge-tunnel connection in the complex mountainous expressway, resulting in a lack of pertinent basis for the design and construction process, which is likely to cause design and construction. Significant economic losses and even threats to the safety of construction workers, the purpose is to provide a design and construction method for expressways connected by reservoirs, banks, bridges and tunnels, to solve the above problems

Embodiment
[0045] like figure 1 Shown, a kind of method for the design and construction of expressway connecting reservoir, bank, bridge and tunnel of the present invention comprises the following steps:
[0046] S1: According to the survey data, set the plane layout and vertical line break of the expressway to generate a preliminary design scheme;
[0047] S2: Taking the area where the curve curvature of the existing old road is greater than the threshold value as the trimming area, and straightening the existing old road in the trimming area;
[0048] S3: Design the construction access road according to the preliminary design scheme and the existing old road after cutting and straightening;
[0049] S4: Carry out tunnel and bridge design according to the preliminary design scheme, and design operational safety guarantee measures;
[0050] S5: Integrate the preliminary design scheme, construction access road design, tunnel and bridge design, and operation safety guarantee design into ...

The invention discloses a method for designing and constructing expressways connected by banks, bridges and tunnels, which comprises the following steps: generating a preliminary design scheme; cutting and straightening existing old roads in the repair area; designing construction access roads; and according to the preliminary design The design of tunnels and bridges, and the design of operation safety guarantee measures; the preliminary design scheme, construction access design, tunnel and bridge design, and operation safety protection measure design are integrated into the construction plan of the expressway connecting the bank, bridge and tunnel; according to the library According to the construction scheme of the expressway connecting the shore bridge and tunnel, the construction will be carried out. The invention relates to a design and construction method for expressways connected by reservoirs, banks, bridges and tunnels. When arranging the route, the topography and geological conditions are combined, and the bridge and tunnel construction procedures, later operation safety and maintenance convenience are considered comprehensively, and the terrain conditions are fully utilized, and avoid Unfavorable geology has adverse effects on expressway operation, and it has wide applicability and is conducive to large-scale promotion.
Description
technical field [0001] The invention relates to expressway design and construction technology, in particular to a method for designing and constructing expressways connected by banks, bridges and tunnels. Background technique [0002] In recent years, more and more mountain expressways have been planned and constructed. Expressways have brought great convenience to mountain traffic. However, since expressways belong to high-grade highways, the requirements for linear indicators are relatively high, and the terrain in mountainous areas is steep and undulating. More and more tunnels and bridges appear. Within the scope of the belt, many expressways are arranged along the river, and the wiring of some sections is extremely difficult. In this case, how to route the expressway, how to implement it, how to rescue it during operation, and how to connect with local roads are all issues that need to be considered overall. If it is not handled properly, it will cause heavy losses. ...
