Along with energy crisis and worsened environment becoming more and more intensively, gas-vehicle receives the unprecedented recognition because of its less emissions, more economical and saving petroleum resource. The research and utilization of gas-vehicle develop quickly all over world. Of course, automotive fuel changing from gasoline and diesel into gas fuel is also carried out blazingly everywhere in our country.

The comprehensive treatment project of Tong Ken landslide consists of whittling slope、anti-landslide pile with anchoring cable、retaining wall、building ground drainages leveling off and calking slope、vegetation protection etc. After managing, under the action of earthquake load and watery the stability coefficient of landslide is up to 1.10.Then, this text researches the structural optimization design of anti-slide pile with anchoring cable. On the condition that the width of section is invariable, the height of section is confirmed by structural optimization method. This will change traditional method to optimize the height of section so that design is simplified and cost is lower.
