室内静力载荷测定仪是岩土工程勘家、建筑地基检测的一种新型测试仪器.可取代野外载荷试验,确定不同深度、不同状态的成层的砂土、粉土、粘性土、淤泥质土、残积土、软质岩地基容许承载力和变形模量.用静力载荷测定仪确定建筑地基容许承载力这一新技术属首创,并于1995年5月20日被国家专利局授予实用新型专利权.室内静力载荷试验与野外静力载荷试验相比,前者结构简单,体积小.重量轻(32kg),携带方便,省力省时,易于操作,性能灵敏稳定,精度高,单位面积压力为0～2500kPa,试验费用为野外载荷试验的4%～5%.室内静力载荷测定仪的问世,对提高测试质量,正确测定地基承载力,确保地基基础设计技术合理,降低勘察成本.提高效益,均具有重要意义.
The indoor static load tester is a new type of testing instrument for geotechnical engineering survey and construction foundation testing. It can replace field load tests to determine layered sand, silt, cohesive soil and silt with different depths and conditions. The allowable bearing capacity and deformation modulus of soil, residual soil and soft rock foundations. The new technology of determining the allowable bearing capacity of building foundations with the static load tester is the first and was granted by the State Patent Office on May 20, 1995. New patent right. Compared with field static load test, the static load test of the former is simple in structure, small in size, light in weight (32kg), easy to carry, saves labor, saves time, is easy to operate, and has stable performance, high precision, and unit area. The pressure is 0 ~ 2500kPa, the test cost is 4% ~ 5% of the field load test. The advent of indoor static load tester, to improve the quality of the test, the correct determination of the bearing capacity of the foundation, to ensure reasonable foundation design technology, reduce survey costs. It is of great significance to increase efficiency.
