the roof decorative tower installed
(1) of bearing capacity of the roof decorative tower foundation: foundation can bear the load capacity.
(2) the roof decorative tower allowable bearing capacity of foundation: promise not to exceed the allowable value of deformation meet the foundation stability requirements and foundation, load of foundation on unit area can bear.
(3) the basic value of bearing capacity of the roof decorative tower foundation: test according to standard methods, without statistical processing of data. By the physical properties of soil bearing capacity standard that check.
(4) value of bearing capacity standard roof decorative tower foundation: under normal circumstances, possible minimum value of bearing capacity, the department according to the standard test method, and by the statistical processing of the obtained data. Can be hit number directly check specification table to determine the bearing capacity by the field identification result and dynamic penetration test of the hammer, can also according to the basic value of bearing capacity is obtained by multiplying the regression coefficient of correction.
(5) the design value of bearing capacity of the roof decorative tower foundation: Foundation in ensuring the stability conditions, the ability to meet the requirements to be able to bear the load settlement of building foundation. Can be made of plastic load directly, also can be obtained by dividing the safety coefficient of ultimate load, or by the standard value of foundation bearing capacity after the foundation width and depth correction determined.
