Summary:The invention discloses an opposite-penetrating double-locking anchor cable supporting system for reinforcing a soft rock pillar of a double-hole highway tunnel. The opposite-penetrating double-locking anchor cable supporting system comprises one or more sets of anchor cable structures anchored on the two sides of the soft rock pillar in an opposite-penetrating mode, each set of anchor cable structure comprises two anchor cables and two extrusion type double-anchor-cable constant-resistance connectors, the two anchor cables penetrate through the two sides of the soft rock pillar in an opposite-penetrating mode and are arranged in parallel, and the two extrusion type double-anchor-cable constant-resistance connectors enable the four ends, exposed out of the two side faces of the soft rock pillar, of the two anchor cables to be anchored together to form a set of anchor cable structure. According to the opposite-penetrating double-locking anchor cable supporting system, the friction forceof the tail portions of
