The tunnel exit section is a stone filled subgrade, and the tunnel mucking can be used as the filling material of the subgrade. The portal of Anhua section of the tunnel is located in the south wing of the "V" shaped valley. The mileage stake number is K187+829, the elevation of the portal floor is 335.23m, the ground elevation is generally between 334 and 355, the topographic slope angle is about 300, the Quaternary overburden is thin, mainly middle back moderately weathered limestone, and Class V surrounding rock. According to the geophysical exploration results, The top of K187+821-K187+845m crushing area is located at 4.45m of the floor at the entrance of Anhua section, and it develops downward to about 55m below the tunnel bottom, which has a great impact on the stability of surrounding rock and is difficult to construct. The portal of Shaoyang section of the tunnel is located on a mountain near the slope toe. The mileage stake number is K188+154, the elevation of the portal floor is 341.46m, the ground elevation is generally between 335-355m, the terrain slope toe is about 550, the Quaternary overburden is thin, mainly medium thick layered moderately weathered limestone, Grade V surrounding rock, with good stability and little construction difficulty.

The accuracy of construction survey meets the requirements of Highway Survey Specification (JTJ061-99). The survey method and result data shall be signed and submitted to the supervising engineer. Construction can be carried out only after being approved by the supervising engineer. Before commencement, the specific positions of subgrade slope toe, cutting top, intercepting ditch, side ditch, berm, borrow pit, spoil ground, etc. shall be set out on the site, and their outlines shall be marked for the supervision engineer's inspection and approval. ⑵ Investigate and test the geology, hydrology, obstacles, and various pipelines within the construction scope before subgrade construction. Representative soil samples are taken from the embankment filling materials in the excavation and borrow areas as shown in the drawings. The test method is in accordance with the Specification for Highway Geotechnical Test (JTJ051-93), and the test items are in accordance with the requirements of the "Technical Specifications". ⑶ Before waterproof and drainage construction, various waterproof and drainage facilities of subgrade shall be well prepared, drainage ditches shall be dug and kept in good drainage condition. ⑷ Before the construction of subgrade works, the trees, shrubs, turf, crop roots and topsoil within 100-300 mm below the original ground within the construction scope shall be removed. And they shall be stacked in the spoil ground or the place approved by the supervising engineer. After the site cleaning is completed, the full pre filling rolling shall be carried out to make the compactness meet the specified requirements. (5) Construction in rainy season Before construction in rainy season, determine the sections where construction in rainy season can be carried out according to the specific conditions of the site, strictly follow the relevant provisions on construction in rainy season in the Technical Specifications for Construction of Highway Subgrade (JTJO33-95), and prepare an implementation organization plan for construction in rainy season, which shall be submitted to the supervision engineer for review and approval.

Shallow foundation pit construction 1. Foundation pit drainage: first dig a sump outside the foundation pit cushion cap, and then dig drainage ditches around to collect the water in the pit along the drainage ditch into the sump, pump the water in the sump out of the pit, and the drain pipe orifice should be 5m away from the edge of the foundation pit to prevent seepage back to the foundation pit, causing slope collapse. When pumping, a special person should be responsible for cleaning the sump, 24 hours of uninterrupted drainage until the completion of the cushion cap construction. 2. The ground around the top of the foundation pit shall be made into a reverse slope, and intercepting ditches shall be set 1m away from the top edge of the foundation pit to prevent rainwater from soaking into the foundation pit. 3. Excavate the foundation pit with an excavator to 20-30cm from the top of the cushion, and over excavation is prohibited. Selection of spoil ground: transported out by dump truck 4. Foundation pit excavation method: sloping excavation, pit wall slope 1:1. If the pit wall is peeled off, the slope can be appropriately increased. The pit bottom is high in the middle and low on both sides. The water will be diverted to the sump to reduce the groundwater level
