施工难度较大可以用英文表示为 "the construction is of high difficulty" 或 "the construction presents a high level of difficulty". 这两个表达方式的意思是一样的,都是指施工难度较大。

其中,"difficulty" 是英文中表示"难度"的单词,"high" 则是形容词,表示"较大"或"高"。

下面是一些例句,希望能帮助你理解这个表达方式的用法:

The construction of the bridge is of high difficulty due to the narrow and unstable terrain. (由于狭窄不稳定的地形,桥的施工难度较大。)
The construction project presents a high level of difficulty as it requires precise and careful planning. (这个施工项目难度较大,因为它需要精细和仔细的规划。)
