If a single support type cannot effectively control the roadway deformation, combined support method, i.e. the combination of two or more support types are used, which is an alternative for roadways at depth and under complex conditions.
The presidential election showed combined support for candidates hostile or even lukewarm to the idea to be tiny.
The inclination values obtained from the two cores combined support the hypothesis of persistent shallow inclinations at Hawaii.
The second Cisalpine Republic, established in June 1800, proved to be a transitional regime, since it lacked the necessary combined support of the moderates and landowners.
Yesterday's turnout is greater than the combined support received by pro-independence parties at those elections, and is in line with support received by all parties in favour of holding an independence consultation.

Just over a year before the next election, combined support for his minority government and its allies, the Left and Green parties, is at its lowest for a decade.
This paper presents a detailed analysis of the equations required to construct the support characteristic curve of a combined support system consisting of closed circular steel sets linked to the periphery of the tunnel by equally spaced prismatic wood blocks.
The paper shows that both the stiffness and maximum load that the combined support system can take increases as the angle between equally spaced wood blocks is decreased (or the number of blocks for the steel section is increased).
The reliability and rationality of a combined support technology including floor anchors, an inverted arch, and anchoring of both sides was verified by mine pressure data and the field observations.
a rock bolting b yieldable steel arch c combined support.
