Chaoguan Expressway Link Avenue New Project
The new project of Chaoguan Expressway Link Avenue is located in the southeast of Guangdong Province, in the west of Shanwei City, under the management committee of Shenzhen Shantou Cooperation Zone. The total length of the line is 13.5km, of which the road section is 5.675km long. The starting point of the road section is located at the A ramp (K0+000) of Chishi Interchange connecting Chaoguan Expressway, and the road along the line is from Puding, Dazhuyuan, Da'an Village, Xiatianxin, Sanjiaokeng to the terminal Bird Farm (K5+700). The total length of the line is 5.675km, the lane is two-way four lane (4 × 3.5m), the design speed is 60km/h, and the line width is 20.5m. The excavation of earth and stone in this section is 441000 m3, and the filling utilization is 273000 m3. According to the geotechnical conditions of the excavation sections along the line, the slope design shall first take safety as the principle. On the premise of not adding special reinforcement measures as much as possible and meeting the greening conditions of the slope, the slope rate will be appropriately steepened to reduce land occupation and damage to natural slope vegetation. When conditions permit, the toe and top of the soil slope shall be subject to arc treatment to better integrate the slope with the surrounding environment. Considering the requirements of slope stability, greening and landscape, the slope rate shall be considered according to different strata and sections.
