山区渠道多数是傍山而行的。由于渠岸两边树木成林,特别是松树较多的地方白蚁对渠岸危害的可能性更大。当然,对内坡的影响不易发现;然而对外坡就不同,危害相当大。如果白蚁在外坡渠岸内做了巢,随着蚁路漫延,就能使渠岸沿蚁路漏水,出现管涌至使渠岸垮坡缺口,造成损失。因此,白蚁对渠岸的危害应引起工程管理人员的注意。发现白蚁破坏迹 Mountain channels are mostly mountain walk. Termites are more likely to be harmed by crevasse because of the trees on both sides of the canals, especially where there are many pine trees. Of course, the impact on the inner slope is not easy to find; however, the outer slope is different and the damage is quite substantial. If the termites nest in the outer bank of the slope, as the ant road is prolonged, it can make the ditches leaking along the ant road, causing the piping to collapse so as to cause the loss. Therefore, the harm of termites to the ditches should attract the attention of project managers. Termite rupture was found
