关于深基坑的支护设计与岩土勘察技术探讨

深基坑支护工程是一种不同于一般的工程构筑物,其所具有的复杂性、可变性以及临时性的特点决定了深基坑支护工程的特殊性。对深基坑支护工程进行支护设计时,不管采取哪种支护设计结构,都要系统仔细地分析和计算支护设计结构的强度、嵌入深度、支护受力及岩土性质,必须要做到结构的可靠以及合理经济受力,进而确保安全。本文结合实例工程,对深基坑的支护设计与岩土勘察技术探讨。

Discussion on Deep Foundation Pit Supporting Design and Geotechnical Investigation Techniques

Deep foundation pit support engineering is different from general engineering structures,it has the complexity,variability,and temporality,which determines the particularity of deep foundation pit support engineering.Design of deep foundation pit support engineering,whether to take what kind of support design structures,should carefully analyze and calculate supporting design structure's strength,embedded depth,the supporting force and geotechnical properties and must achieve reliable structure and reasonable and economic force,thus ensuring safety.In this paper,the example project,deep foundation pit supporting design and geotechnical investigation techniques were explored combining with example of engineering.
