1. Common engineering geological problems in Shenzhen area include uneven settlement of soft soil foundation, karst ground collapse, collapse and landslide of sand-shale interbedded weak strata and their influence on engineering piles, the influence of NW fracture of granite in late Mesozoic on engineering piles, and the influence of NE fracture on engineering piles.
2. Damage loss statistics. Investigate and count the number of buildings affected by the disaster, including ground buildings (sub-buildings (blocks), bungalows (blocks), workshops (blocks) and fencesWalls (walls), underground structures (tunnels, civil defences) and roads. Investigation and statistics of the damage degree of the affected buildings, divided into building types, damage degree (serious, moderate, minor). The direct economic loss caused by ground cracks is calculated (ten thousand yuan).
3, usually such information includes terrain, hydrology, geology, rock and soil, landform, vegetation and land use information. The information was obtained through field investigation and aerial film interpretation. The judgment of different experts on the influence of environmental factors on landslide is different, which mainly depends on their understanding and experience of landslide. The subjective nature of this judgment and the absence of definite criteriaThe heuristic method has obvious defects.
4, the damage objects of different geological disasters are different, resulting in different economic losses. Collapse, landslide, debris flow damage range, almost involving all types of disaster, including: houses, railways, highways, Bridges, lifeline projects, water conservancy projects, structures, waterways, crops and trees, equipment, materials, indoor property, land resources, etc.
5, the basement uplift not only causes the deformation of the enclosure system of the foundation pit itself, but also causes the surrounding surface settlement, and has an adverse impact on the surrounding buildings.
6, according to variousThe damage and influence of natural geological processes and mining activities on geological environment are discussed. To predict and evaluate the environmental geological problems that may be caused by the mining of mineral deposits, such as the drop of regional groundwater level, mountain cracking, landslide, debris flow, surface subsidence and collapse, surface water and groundwater pollution, pollution by radioactive and other harmful substances, and put forward suggestions for prevention and control.
