当代建筑工程正在向建筑物高、占地面积少、经济效益好的方向发展。建筑物的特点对基础工程也提出了新的要求。城市、交通、水电、工矿、国防建设工程的基础正在向大型和深部发展；有的工程要建在地下和水下；有的工程要建在海港、海滨；塌方、滑坡事故隐患要求防治；基础施工要求无噪音、振动小、无污染，并且要求高速度、高质量、低成本和安全施工。而目前我国建筑工程的基础施工远远不能满足上述要求。主要是：土方量大，机械化程度低；工期长，造价高。改变我国基础工程施工的面貌，必须 Contemporary construction projects are moving toward higher buildings, less floor space, and better economic returns. The characteristics of the building also put forward new requirements for the basic project. The foundations of cities, transportation, hydropower, mining, and national defense construction projects are being developed into large and deep areas; some projects are to be built underground and under water; some projects are to be built in seaports and the seashore; hidden dangers of landslides and landslides require prevention and control; The construction requirements are noiseless, vibration-free, non-polluting, and require high-speed, high-quality, low-cost, and safe construction. At present, the basic construction of China’s construction projects is far from meeting the above requirements. Mainly: Large amount of earthwork, low degree of mechanization, long construction period and high construction cost. To change the face of our country’s basic construction work, we must
